Yes. An employer in the Philippines may issue a Notice to Explain (NTE) for alleged unauthorized overtime, even if the employee says the overtime happened because management increased the workload. But the more important question is whether the NTE has a valid basis, whether the company’s overtime policy was clear and consistently enforced, whether the overtime was actually required or tolerated by the employer, and whether any disciplinary action would be fair under Philippine labor law.

In many workplaces, this situation happens when management adds deadlines, extra accounts, understaffed shifts, or urgent deliverables, but still requires prior approval before overtime. The employee then works beyond regular hours to finish the job and later receives an NTE for “unauthorized overtime.” This can feel unfair, especially when the extra work was not self-created. Under Philippine law, however, both sides have obligations: the employer may regulate overtime, but it must also pay compensable overtime that it required, allowed, or benefited from, and it cannot discipline an employee arbitrarily.

What an NTE Means in a Philippine Workplace

A Notice to Explain, often called an NTE or “show cause memo,” is a written notice requiring an employee to explain an alleged workplace violation.

An NTE is not yet a dismissal. It is usually the first step in an administrative investigation. It gives the employee a chance to answer before the employer decides whether to impose a penalty.

For an NTE to be fair, it should state:

the specific act complained of;
the date, time, and circumstances of the alleged violation;
the company rule allegedly violated;
the possible penalty;
the deadline to submit a written explanation; and
the employee’s opportunity to be heard.

For termination cases based on just causes, the Supreme Court in King of Kings Transport, Inc. v. Mamac explained that the first written notice must contain the specific grounds and give the employee a reasonable opportunity to submit an explanation. The DOLE’s Department Order No. 147-15 similarly requires due process before termination and treats a “reasonable period” to answer as at least five calendar days in just-cause termination cases. (Lawphil)

Even when the company is not yet planning to dismiss the employee, good HR practice is to follow the same basic fairness standards.

Can an Employer Require Prior Approval Before Overtime?

Yes. An employer may generally require employees to secure prior approval before rendering overtime.

Overtime affects payroll, staffing, productivity metrics, client billing, workplace safety, and budget control. Because of this, many Philippine companies have rules such as:

overtime must be approved by the immediate supervisor;
an overtime authorization form must be filed before the work is done;
overtime without prior approval may be subject to discipline;
only urgent or management-directed overtime is allowed;
overtime must be supported by timekeeping records and task reports.

A rule requiring approval is not automatically illegal. The employer has management prerogative, meaning the right to manage business operations, assign work, control costs, and enforce reasonable workplace rules.

But management prerogative is not absolute. A company rule must be:

Requirement	What It Means in Practice
Lawful	It must not defeat statutory labor rights, such as overtime pay for covered employees.
Reasonable	It must be connected to a legitimate business purpose.
Known to employees	The rule should be in the handbook, memo, contract, portal, or clearly communicated policy.
Consistently enforced	The company should not punish one employee while tolerating the same conduct from others.
Fairly applied	The penalty must be proportional to the alleged violation.

So the employer can require prior approval. But if the employer increased the workload, imposed urgent deadlines, knew the employee was working late, accepted the output, and then refused both payment and fairness, the situation becomes legally problematic.

Philippine Law on Overtime Work

The basic rule is found in Article 87 of the Labor Code: work may be performed beyond eight hours a day, provided the employee is paid overtime compensation equivalent to the regular wage plus at least 25%. For work beyond eight hours on a holiday or rest day, the additional compensation is generally at least 30% of the applicable holiday or rest day rate. (Lawphil)

Overtime rules usually apply to rank-and-file employees covered by the Labor Code’s hours-of-work provisions. Some employees may be excluded, such as managerial employees, certain field personnel, and others not covered by normal hours-of-work rules under Article 82.

Regular overtime rate

For ordinary overtime on a regular workday:

hourly rate + at least 25% of hourly rate

Example:

Item	Amount
Daily wage	₱800
Regular hourly rate, assuming 8 hours	₱100
Overtime premium, 25%	₱25
Overtime hourly rate	₱125

If the employee worked two compensable overtime hours, the overtime pay would be ₱250.

Overtime on rest days and holidays

Overtime on rest days, special non-working days, and regular holidays is more complicated because premium pay or holiday pay may first apply before overtime is computed. The DOLE’s Workers’ Statutory Monetary Benefits Handbook is the practical reference commonly used by HR, payroll officers, and labor inspectors for these computations. (BWC Dole)

Unauthorized Overtime vs. Unpaid Overtime

It is important to separate two issues:

Was the employee allowed or required to work overtime?
If the overtime was worked, must the employer pay it?

These are related but not identical.

An employee may violate a reasonable company policy by failing to get prior approval. But if the employer actually required, permitted, or knowingly benefited from the overtime work, the employer may still have to pay the compensable overtime.

In other words, an employer cannot usually say:

“You worked overtime for our business, we accepted the work, but we will not pay because the overtime was unauthorized.”

That position is risky, especially if the supervisor knew about the work, assigned the workload, monitored the late work, received the output, or allowed the practice to continue.

On the other hand, an employee also should not assume that simply staying late automatically creates a right to overtime pay in every situation. The employee must be able to show that overtime work was actually performed and was connected to the job. The Supreme Court has repeatedly required proof that overtime was actually rendered before overtime pay may be awarded. (Lawphil)

What If the Workload Was Increased?

This is the heart of the issue.

If management increased the workload, the employee’s best defense is usually not “I can work overtime whenever I want.” The stronger defense is:

“The overtime became necessary because of management-assigned workload, urgent deadlines, understaffing, or instructions, and the company knew or should have known that the work could not reasonably be completed within regular hours.”

This matters because discipline for unauthorized overtime should consider the real circumstances.

Scenario 1: The employer increased workload but also gave clear instructions not to work overtime

Example: A supervisor says, “Do what you can until 5:00 p.m. Do not render overtime unless I approve it.” The employee stays until 9:00 p.m. without informing anyone.

In this case, the NTE may have a stronger basis. The employee may still explain that the workload was heavy, but the employer can argue that the employee ignored a clear instruction.

Scenario 2: The employer increased workload and imposed a deadline that required overtime

Example: The company assigns a same-day report at 4:00 p.m., due by 9:00 a.m. the next day, and the supervisor knows the employee must stay late to finish it.

In this case, the employee has a stronger defense. The employer cannot realistically create the conditions requiring overtime, accept the output, and then treat the employee as if the overtime was purely voluntary.

Scenario 3: The employer regularly tolerated overtime without prior approval

Example: For months, employees worked late, submitted outputs after hours, and managers praised or accepted the work. Only later did HR issue NTEs for unauthorized overtime.

This weakens the employer’s position. A company policy may exist on paper, but inconsistent enforcement can make discipline appear selective, unfair, or arbitrary.

Scenario 4: The employee inflated time records or stayed late for personal reasons

Example: The employee clocks out late but is not actually working, or stays in the office for convenience and claims overtime.

In this case, an NTE may be justified. Overtime pay requires actual work, not merely presence in the workplace.

Can Refusal to Work Overtime Be Insubordination?

Sometimes, yes — but only in specific situations.

Under Article 89 of the Labor Code, an employer may require overtime work in certain emergency or urgent situations, such as war or national emergency, urgent work on machines or installations to avoid serious loss, work necessary to prevent loss or damage to perishable goods, and similar circumstances. (Lawphil)

In Lagatic v. NLRC / Graphics, Inc., the Supreme Court held that an employee’s unjustified refusal to render overtime may constitute insubordination where the overtime order was justified under Article 89 and connected to contractual commitments to clients. (Lawphil)

But this does not mean employers can freely force overtime every day. The legality of mandatory overtime depends on the facts. Ordinary workload problems, poor staffing, or recurring unrealistic deadlines are not automatically “emergency overtime” under Article 89.

Can the Employer Discipline the Employee for Unauthorized Overtime?

Yes, if all of the following are present:

There is a clear company rule requiring prior approval.
The rule was made known to the employee.
The employee violated the rule.
The violation was not caused or effectively required by management’s own instructions.
The penalty is reasonable and proportionate.
The employer observes due process.

Discipline may include coaching, warning, written reprimand, suspension, or, in extreme and repeated cases, dismissal. But dismissal for a first-time unauthorized overtime issue may be too harsh unless there are aggravating factors such as fraud, falsification of time records, repeated violations, deliberate disobedience, or serious loss to the employer.

Under Article 297 of the Labor Code, just causes for termination include serious misconduct, willful disobedience of lawful orders, gross and habitual neglect of duties, fraud or willful breach of trust, commission of a crime against the employer or immediate family, and analogous causes. (Lawphil)

For “willful disobedience” to justify serious discipline, the order must generally be lawful, reasonable, known to the employee, connected with work, and intentionally disobeyed.

If the employee worked overtime in good faith to complete an increased workload, without fraud or bad intent, that may reduce or defeat the basis for a severe penalty.

What Should the Employee Do After Receiving an NTE?

Do not ignore the NTE. Even if it feels unfair, silence may be treated against you.

1. Read the NTE carefully

Check whether it states:

the exact date of the alleged unauthorized overtime;
the number of overtime hours questioned;
the policy allegedly violated;
the possible penalty;
the deadline to answer;
whether a hearing or conference will be held.

If the NTE is vague, mention this politely in your written explanation.

2. Gather your documents

Useful evidence includes:

Evidence	Why It Helps
Workload assignments	Shows the amount of work given.
Emails, chats, tickets, or task logs	Shows deadlines and instructions.
Time records or biometric logs	Shows actual hours worked.
Prior overtime approvals	Shows company practice.
Messages to supervisor	Shows you informed management.
Submitted reports or deliverables	Shows the company benefited from the work.
Team workload data	Shows understaffing or unusual work volume.
Employee handbook or overtime policy	Shows whether the rule was clear.

Screenshots should ideally show the date, sender, recipient, and full context. Avoid editing messages in a way that makes them misleading.

3. Submit a written explanation on time

If the NTE gives less than five calendar days and the possible consequence is termination, you may respectfully request more time, citing the need to gather records and prepare your explanation.

Keep the tone factual. Do not insult HR or your supervisor. The goal is to create a clear record.

4. Explain the increased workload

Be specific. Instead of saying, “I had too much work,” write something like:

“On March 4, I was assigned 38 tickets instead of the usual 15–18.”
“The deadline was moved from Friday to Wednesday.”
“Two team members were absent, and I was asked to cover their pending accounts.”
“The report was required before the client meeting the next morning.”
“I informed my supervisor through Teams at 5:42 p.m. that I could not finish within regular hours.”

Specific facts are stronger than emotional statements.

5. Address the approval issue directly

If you forgot to request approval, acknowledge it carefully but explain the context:

“I understand the company’s overtime approval procedure. In this instance, I continued working because the assigned deliverables were urgent and had to be submitted that evening. I did not intend to violate policy or claim improper overtime. Going forward, I will secure written approval before rendering overtime, and I respectfully request that workload deadlines be aligned with the approval process.”

If you requested approval verbally or through chat, attach proof.

6. Ask for a hearing if needed

If the facts are disputed, ask for a chance to explain in a conference. Under due process principles, the employee should be given a meaningful opportunity to be heard before a serious penalty is imposed. (Lawphil)

Sample Structure for an Employee’s NTE Explanation

Use this structure if you need to answer an NTE for unauthorized overtime:

Acknowledge receipt
- State the date you received the NTE.
- State that you are submitting your explanation within the required period.
Briefly deny bad faith
- Say you did not intend to violate company policy or improperly claim overtime.
Explain the workload
- Describe the increased workload, urgent deadline, staff shortage, or management instruction.
Show management knowledge
- Identify who assigned the task, who monitored it, and who received the output.
Attach evidence
- Refer to emails, chat messages, tickets, logs, and time records.
Address the policy
- If approval was requested, say how.
- If not, explain why the situation was urgent and undertake to comply moving forward.
Request fairness
- Ask that the explanation and evidence be considered before any penalty is imposed.

Sample Explanation Language

You can adapt the following:

I respectfully submit this explanation regarding the alleged unauthorized overtime on [date]. I understand the company’s policy requiring prior approval before overtime is rendered. I did not intend to disregard this policy or claim overtime improperly.

The overtime happened because of the workload assigned on that date. Specifically, [describe task, deadline, volume, or instruction]. Based on the time required to complete the assignment and the deadline given, I could not reasonably finish the work within regular hours.

My supervisor/manager was aware of the assignment and the deadline. The completed work was submitted to/accepted by [name/team/client] on [date/time]. Attached are copies of [emails/chats/task logs/time records] showing the assignment, deadline, and completion of the work.

If the company finds that a separate written approval should have been secured, I respectfully ask that the circumstances be considered. The overtime was done in good faith to complete company-assigned work, not for personal benefit or to disregard company rules. Going forward, I will make sure to secure written overtime approval before rendering overtime and will immediately inform my supervisor if assigned work cannot be completed within regular hours.

What Employers Should Check Before Issuing an NTE

Employers should avoid using an NTE as a reflex response to overtime cost. Before issuing one, HR should review:

Was the overtime policy clearly communicated?
Was the employee trained on the approval process?
Did the supervisor assign work that reasonably required overtime?
Did the supervisor know or tolerate the overtime?
Did the company accept the output?
Were other employees treated the same way?
Was the employee previously warned?
Is there evidence of fraud, padding, or falsification?
Is the proposed penalty proportionate?
Has the company paid or properly evaluated compensable overtime?

A fairer HR approach is often to address both sides:

process violation: failure to secure prior approval; and
management issue: workload planning, staffing, deadline setting, and supervisor approval practices.

If the company disciplines employees but ignores the workload system that caused the overtime, the dispute may escalate.

Can the Employer Refuse to Pay Unauthorized Overtime?

Not automatically.

If the employee is covered by overtime rules and actually performed work beyond eight hours, the employer should carefully evaluate whether the overtime was:

expressly authorized;
impliedly authorized;
required by workload or deadline;
known by the supervisor;
accepted through completed deliverables; or
part of a tolerated company practice.

If yes, non-payment may expose the employer to a money claim.

However, the employee must still prove the overtime work. In labor cases, time records, payroll records, work logs, emails, and credible testimony matter. The Supreme Court has recognized that entitlement to overtime pay must first be established by proof that overtime work was actually performed. (Lawphil)

What If the Employee Is a Manager or Supervisor?

Not all employees are entitled to overtime pay.

Under the Labor Code, certain categories may be excluded from the hours-of-work provisions, including managerial employees and officers or members of a managerial staff who meet the legal tests.

But job title alone is not controlling. Calling someone “manager” does not automatically remove overtime rights. What matters is the actual nature of the work, authority, discretion, and role.

A “team lead,” “supervisor,” or “assistant manager” may still be overtime-covered if the person does not truly exercise managerial powers under labor standards rules.

For employees in BPOs, shared services, retail, logistics, hospitality, healthcare, construction, and manufacturing, this distinction often becomes important because titles may not match actual authority.

What If the Employee Is Working From Home?

Remote work does not erase overtime rules.

If a covered employee working from home performs work beyond eight hours with the employer’s knowledge, approval, or benefit, overtime may still be compensable. The practical problem is proof.

Employees working remotely should keep:

screenshots of assigned tasks;
system logs;
emails showing time-sensitive instructions;
chat messages after regular hours;
call logs;
ticketing system records;
submitted files with timestamps;
approvals or acknowledgments from supervisors.

Employers should also create clear remote-work policies on work hours, overtime approval, after-hours messaging, and timekeeping.

What If the Employer Increased Workload but Says “No Overtime Allowed”?

This is common.

A company may say overtime is not allowed, but still assign work that cannot realistically be finished within regular hours. When this happens, the employee should avoid silently working late. Instead, create a written record before overtime happens.

For example:

“Hi [Supervisor], I can continue working on the additional reports, but based on the current volume, I will not be able to finish all assigned items by 6:00 p.m. Please confirm whether I should prioritize only [A and B] today or render overtime to complete [C and D] as well.”

This kind of message protects both sides. It gives management a choice:

approve overtime;
reduce the workload;
move the deadline;
reassign tasks;
accept partial completion.

If the supervisor does not reply but later demands completion, the employee’s written message may become important evidence.

Possible Outcomes After an NTE

After the employee submits an explanation, the employer may:

Outcome	What It Means
No penalty	HR accepts the explanation.
Coaching or reminder	The matter is treated as a process issue.
Written warning	The company finds a violation but imposes a light penalty.
Suspension	Possible for repeated or more serious violations, depending on policy.
Non-payment dispute	The company refuses overtime pay, which may become a labor standards issue.
Termination	Possible only if there is a just cause and due process; often excessive for a simple first-time approval lapse.

If dismissal is imposed despite weak evidence, inconsistent enforcement, or management-caused overtime, the employee may consider filing an illegal dismissal complaint.

Where to File a Labor Complaint

Most labor disputes now pass through the Single Entry Approach (SEnA), a mandatory conciliation-mediation mechanism designed to resolve labor issues quickly and inexpensively. SEnA was institutionalized under Republic Act No. 10396 (2013), and DOLE’s current rules continue to use a 30-calendar-day conciliation-mediation period for labor and employment disputes. (Lawphil)

Practical filing options

Concern	Where to Start	Notes
Unpaid overtime only	DOLE Regional Office or SEnA desk	Good for labor standards and monetary settlement discussions.
Illegal suspension or dismissal	SEnA, then NLRC if unresolved	Illegal dismissal cases are generally handled by Labor Arbiters after mandatory conciliation.
Retaliation after raising overtime concerns	SEnA/NLRC, depending on facts	Keep documents showing the timing and reason for retaliation.
Many employees affected	DOLE inspection or group RFA	Useful where overtime non-payment is systemic.
Unionized workplace	Grievance machinery may apply	CBA procedures may come first for policy disputes.

SEnA can often be filed through a DOLE office or online platform, depending on the region and available systems. The typical first step is a Request for Assistance (RFA), followed by conferences conducted by a Single Entry Assistance Desk Officer.

Documents to Prepare Before Filing a Complaint

If the issue escalates, prepare these documents early:

Document	Why It Matters
NTE and written explanation	Shows the accusation and your response.
Notice of decision, if any	Shows the penalty imposed.
Employment contract	Shows position, salary, and work terms.
Company handbook or overtime policy	Shows the rule allegedly violated.
Payslips	Shows whether overtime was paid.
Daily time records or biometric logs	Shows hours worked.
Emails, chats, task tickets	Shows workload and deadlines.
Proof of submitted work	Shows the company benefited from the overtime.
Prior approvals or past practice	Shows consistency or tolerance.
Witness names	Helps prove actual workplace practice.

For online evidence, keep original files when possible. Screenshots help, but downloadable logs, email headers, system exports, and unedited conversation threads are stronger.

Common Mistakes Employees Make

Ignoring the NTE

Do not assume the NTE is harmless. Failure to answer may allow the employer to decide based only on management’s version.

Admitting too much without context

Avoid writing, “I admit I violated the policy,” without explaining why the overtime happened. A better approach is to acknowledge the policy while explaining good faith, workload, urgency, and management knowledge.

Making emotional accusations

Statements like “HR is corrupt” or “my manager is evil” rarely help. Stick to facts, dates, documents, and instructions.

Claiming overtime without proof

If you claim unpaid overtime, be ready to show actual work performed beyond eight hours. Mere office presence is not enough.

Continuing unauthorized overtime after the NTE

After receiving an NTE, do not repeat the same conduct. Send written workload-priority messages instead.

Common Mistakes Employers Make

Treating all unauthorized overtime as misconduct

Some overtime is truly unauthorized. Some is management-created. HR should distinguish between the two.

Refusing to pay because approval was missing

A prior-approval rule may support discipline, but it does not automatically erase the obligation to pay compensable overtime actually worked for the employer’s benefit.

Ignoring supervisor knowledge

If supervisors assign urgent work, monitor employees after hours, and accept late outputs, the company may have difficulty claiming complete lack of authorization.

Applying the policy selectively

If only one employee is punished while others regularly do the same thing, the discipline may appear discriminatory or unfair.

Jumping to termination

Termination requires just cause and due process. For many first-time overtime approval lapses, dismissal may be disproportionate.

Frequently Asked Questions

Can my employer issue an NTE because I worked overtime without approval?

Yes. An employer may issue an NTE if it believes you violated a company rule requiring prior approval for overtime. But you have the right to explain why the overtime happened, especially if the workload, deadline, or supervisor’s instructions made overtime necessary.

Does unauthorized overtime still have to be paid in the Philippines?

It may still have to be paid if you are covered by overtime rules and the employer required, allowed, knew of, or benefited from the overtime work. Lack of prior approval may be a policy issue, but it does not automatically cancel statutory overtime pay.

What should I write in my explanation to an NTE for unauthorized overtime?

Explain the workload, deadline, instructions, and why the work could not be completed within regular hours. Attach proof such as emails, chats, task logs, time records, and submitted outputs. Keep the tone respectful and factual.

Can I be dismissed for unauthorized overtime?

Dismissal is possible only in serious cases, such as repeated violations, willful disobedience, fraud, falsified time records, or serious loss to the employer. For a first-time good-faith overtime issue caused by increased workload, dismissal may be too harsh.

What if my supervisor verbally told me to finish the work?

State that in your explanation and identify when, where, and how the instruction was given. If there are chats, emails, call logs, or witnesses, mention and attach them. Verbal instructions are harder to prove, but they still matter.

What if the company says overtime is not allowed but keeps giving impossible deadlines?

Send a written message before working late. Ask whether you should render overtime, prioritize certain tasks, move the deadline, or leave the unfinished work for the next day. This creates a record that the workload problem was raised.

Can my employer make me work overtime?

In certain emergency or urgent situations under Article 89 of the Labor Code, an employer may require overtime. But ordinary recurring workload problems are not automatically emergency overtime. The facts matter.

How many days should I be given to answer an NTE?

For just-cause termination cases, DOLE Department Order No. 147-15 treats a reasonable period as at least five calendar days from receipt of the first written notice. If your NTE may lead to dismissal and you were given less time, you may respectfully request an extension.

Where can I complain if my overtime is unpaid?

You may start with SEnA through DOLE, NCMB, or NLRC channels, depending on the issue and location. If conciliation fails and the issue involves illegal dismissal or larger claims, the matter may proceed to the NLRC.

Can foreign employees in the Philippines file labor complaints?

Yes, foreign employees working in the Philippines may generally seek labor remedies if an employer-employee relationship exists and Philippine labor law applies. Immigration status, work permits, contract terms, and the employer’s location may affect the practical handling of the case, so documents are especially important.

Key Takeaways

An employer may issue an NTE for unauthorized overtime, but the employee has the right to explain.
A company may require prior overtime approval, but the rule must be lawful, reasonable, known, consistent, and fairly applied.
Increased workload, urgent deadlines, understaffing, and supervisor knowledge can be strong defenses.
Unauthorized overtime may still be compensable if the employer required, allowed, knew of, or benefited from the work.
Employees should answer the NTE on time, attach evidence, and explain the workload clearly.
Employers should investigate the real cause of the overtime before imposing discipline.
Termination for a simple first-time overtime approval lapse may be disproportionate unless there is willful disobedience, fraud, repeated violation, or serious misconduct.
If the dispute escalates, the usual first step is SEnA, a 30-calendar-day conciliation-mediation process under Philippine labor dispute rules.
