A move from one company to its “sister company” may look like a simple internal reassignment, especially when the companies share owners, managers, offices, or payroll staff. Under Philippine law, however, two separately incorporated companies are generally two separate employers. Moving from Company A to Company B may therefore end the first employment relationship and create a new one. The safest document is often a written, three-party transfer or employment-assumption agreement—not a bare resignation letter—because it can clearly preserve seniority, regular status, salary, leave credits, retirement service, and other benefits.

Is a Transfer to a Sister Company Really an Employee Transfer?

The answer depends on whether the employee will remain under the same legal employer.

A corporation has a legal personality separate from its shareholders, parent company, subsidiaries, and affiliated corporations. This remains true even when the companies have the same owners or belong to the same corporate group under Republic Act No. 11232, the Revised Corporation Code of 2019. (Lawphil)

Arrangement	Usual legal effect
Transfer to another branch, department, project, or office of the same corporation	Normally an internal transfer under the same employer
Transfer to a separately incorporated sister company	Usually termination of employment with the first company and commencement of employment with the second
Temporary assignment while the original company remains the employer and continues payroll	May be a secondment rather than a change of employer
Transfer following a statutory merger or consolidation	Governed by the merger documents, corporate law, labor law, and the employee’s consent
Transfer to a contractor, manpower agency, or employer-of-record company	Normally creates a different legal employer and requires separate analysis

Check the exact corporate names on the employee’s employment contract, payslips, BIR Form 2316, SSS records, PhilHealth records, company ID, and Certificate of Employment. Brand names and group names can be misleading. “ABC Group” may consist of several corporations with different Securities and Exchange Commission registrations, taxpayer identification numbers, payrolls, and legal obligations.

Philippine Law on Employee Transfers

Internal transfers under the same employer

An employer generally has the management prerogative to transfer or reassign an employee for legitimate business reasons. A valid internal transfer normally involves a position of equivalent rank or salary and does not result in:

Demotion in rank;
Reduction of salary, allowances, or benefits;
Unreasonable inconvenience or prejudice;
Discrimination or bad faith;
Punishment disguised as reassignment; or
Conditions so unfavorable that the employee is effectively forced to resign.

The Supreme Court has repeatedly explained that a transfer becomes unlawful when it is unreasonable, inconvenient, prejudicial, discriminatory, made in bad faith, or accompanied by demotion or diminution of compensation and benefits. (Lawphil)

These management-prerogative rules apply most clearly when the legal employer remains the same. They do not automatically authorize Company A to place its employee permanently under Company B.

A sister company cannot simply take over the employee

In BPI v. BPI Employees Union-Davao Chapter, the Supreme Court emphasized that employment is a personal and consensual relationship. It stated that a corporation cannot unilaterally transfer employees to another employer as though they were company property. Both the new employer and the employee must agree to the new employment relationship. (Supreme Court E-Library)

The same practical principle appeared in Retuya v. Dumarpa. Employees continued working in the same office, doing the same jobs and receiving the same salaries, but under another sister company. The Supreme Court still found that their previous employment had been terminated. Without their consent, they became new employees of the other corporation and lost their former status and benefits. The Court said the dispute might have been avoided had the old employment been legally ended and the new employment properly constituted with the employees’ consent. (Supreme Court E-Library)

The practical rule is therefore:

A change in the legal entity employing the worker is not merely an internal transfer simply because the companies are related.

Resignation Versus a Transfer Agreement

There is no single document officially called a “transfer agreement” under the Labor Code. Companies may structure the arrangement through contracts, provided their terms do not violate labor laws, public policy, or minimum employment standards. Articles 1305 and 1306 of the Civil Code recognize freedom of contract, while Article 1311 generally provides that contracts bind the parties who entered into them. (Lawphil)

The two common approaches have significantly different consequences.

Issue	Resignation followed by new employment	Three-party transfer or assumption agreement
End of employment with Company A	Clearly ends through voluntary resignation	Ends or transitions on agreed terms
Consent of employee	Shown by resignation and acceptance of new offer	Expressly documented in one agreement
Recognition of previous service	Not automatic	Can be expressly preserved
Regular employment status	May be treated as a new hire unless protected in writing	Can state that the employee remains regular from day one
Retirement service	May restart	Can be credited from the original hiring date
Leave credits	Usually paid, forfeited, or handled under old policy	Can be transferred or financially assumed
Separation pay	Generally unavailable in voluntary resignation	Can be negotiated or specifically provided
Liability for old benefits	Usually remains with Company A	Can be allocated between Companies A and B
Risk to employee	Higher if the new contract is unsigned or benefits are unclear	Lower when all material rights are specifically stated

When resignation may be acceptable

A resignation-and-rehire arrangement is not automatically illegal. It may work when:

The employee genuinely agrees to leave Company A;
Company B has already issued a signed and unconditional employment contract;
The new contract clearly states the job, salary, benefits, regular status, and start date;
Company A properly pays all amounts due upon separation;
The employee understands which benefits will restart and which will continue; and
There is no coercion, deception, or attempt to defeat security of tenure.

Under Article 300 of the Labor Code, formerly Article 285, an employee who resigns without a legally recognized just cause ordinarily gives at least one month’s written notice. The employer may accept a shorter period or waive the notice requirement. An employee who leaves without the required notice may potentially be liable for proven damages, although this is different from an employer automatically deducting an arbitrary “penalty” from final pay. (Lawphil)

A voluntarily resigning employee is generally not entitled to statutory separation pay unless it is provided by the employment contract, collective bargaining agreement, established company practice, or a specific negotiated arrangement. (Supreme Court E-Library)

Why a bare resignation can be risky

A short resignation letter saying “I voluntarily resign effective today” may unintentionally confirm that:

The employee chose to end the relationship;
Company A did not dismiss the employee;
Company A made no promise to preserve seniority;
Company B is free to treat the employee as newly hired;
Separation pay is not due;
Retirement service under Company A has ended; and
The employee accepted a clean break between the companies.

The greatest danger is the sequence “resign first, contract later.” Once the resignation is effective, Company B may delay the start date, change the compensation package, impose probationary status, or withdraw the offer. The employee may then have difficulty proving that the resignation depended on specific promises.

A resignation should not be signed until the employee has received the final transfer agreement or employment contract signed by authorized representatives of the relevant companies.

What a Proper Sister-Company Transfer Agreement Should Contain

The best structure is usually a tripartite agreement signed by:

The employee;
The current employer; and
The sister company that will become the new employer.

The agreement should address the following matters clearly.

1. Exact identity of all parties

Use the full SEC-registered corporate names, principal office addresses, and authorized representatives. Avoid relying only on trading names or group names.

2. Employee’s informed consent

The agreement should state that the employee knowingly agrees to end or transfer the employment relationship and accept employment with the new company. Consent should not be buried in a quitclaim or clearance form.

3. Effective dates and absence of a service gap

Specify:

Last day under Company A;
First day under Company B;
Whether there will be any unpaid gap; and
Which company is responsible for salary and benefits on the transition date.

4. Recognized original employment date

A strong continuity clause may state:

For purposes of seniority, retirement, separation benefits, service awards, leave entitlement, notice periods, and other length-of-service benefits, Company B shall recognize the employee’s original employment date of [date].

Avoid vague language such as “service may be recognized subject to company policy.” List the exact purposes for which prior service will count.

5. Regular status and probation

The agreement should say whether the employee will be regular immediately. An employee who has already performed the same work for years should be cautious about accepting a fresh six-month probationary period without a legitimate explanation.

Prior regular status with Company A does not always become regular status with Company B automatically because they are separate employers. It must be protected in the agreement.

6. Compensation and job terms

State the complete package:

Basic monthly salary;
Allowances;
Job title and grade;
Reporting line;
Workplace or remote-work arrangement;
Working hours;
Overtime eligibility;
Incentives and commissions;
Bonus treatment;
Company car, housing, or communication benefits; and
HMO or insurance coverage.

A statement that “all existing benefits will continue” can create disputes when the companies have different benefit plans.

7. Accrued leave and other balances

The agreement should state whether unused vacation or service incentive leave will be:

Paid by Company A;
Carried over to Company B;
Converted into a starting leave balance; or
Partly paid and partly transferred.

It should also address expense reimbursements, salary loans, company loans, cash advances, and pending commissions.

8. Retirement and separation benefits

Retirement plans often define service by reference to employment with the specific plan sponsor. A promise to recognize seniority in ordinary HR records may not automatically amend a separately administered retirement plan.

The agreement should specify:

Whether prior service counts under Company B’s retirement plan;
Whether Company A will transfer or fund the related liability;
Whether the employee receives a vested benefit from Company A;
How future separation pay will be computed; and
Which salary rate will apply to the entire credited service period.

9. Collective bargaining and union rights

If the employee belongs to a bargaining unit, transfer to another corporation may affect:

Union membership;
Coverage under the collective bargaining agreement;
Union dues;
Grievance rights;
Seniority rankings; and
Negotiated benefits.

The Supreme Court has recognized that absorbed employees may face new working conditions, company policies, and collective bargaining arrangements even when their prior service is credited. (Supreme Court E-Library)

10. Allocation of liabilities

The document should identify which company is responsible for:

Unpaid wages;
Prorated 13th-month pay;
Leave conversion;
Bonuses and commissions earned before the transfer;
Retirement liabilities;
Pending reimbursement claims;
Government contributions; and
Claims arising before the effective date.

An internal promise between the sister companies is not enough unless the employee can enforce it or is expressly made a party or beneficiary.

11. Quitclaim language

Do not combine the transfer agreement with an unlimited waiver stating that the employee has no present, future, known, or unknown claims unless all amounts have been calculated and explained.

Philippine courts do not automatically invalidate quitclaims. A quitclaim may be enforced when it was signed voluntarily, with full understanding, and in exchange for reasonable consideration. An unconscionable or coerced waiver, however, may be rejected. (Lawphil)

Step-by-Step Process for a Safe Employee Transfer

Confirm whether the companies are legally separate. Compare the corporate names and TINs shown on the employment contract, payslip, BIR Form 2316, and government contribution records.
Request a written transfer proposal. It should identify the new employer, position, compensation, effective date, status, and treatment of prior service.
List every benefit linked to length of service. Include retirement, separation pay, leave entitlement, service awards, bonus eligibility, HMO dependents, stock plans, and notice periods.
Choose the proper structure. Decide whether the arrangement will be a tripartite transfer agreement, resignation with a protected rehire agreement, secondment, or employer-initiated separation followed by new employment.
Complete negotiations before signing a resignation. The new employer’s authorized representative should sign the final employment contract or transfer agreement first or simultaneously.
Obtain corporate authorization. Confirm that the signatories have authority to bind both companies. This may be supported by a secretary’s certificate, board resolution, or written delegation of authority.
Sign all transition documents together. These may include the transfer agreement, new employment contract, resignation or separation acknowledgement, benefit schedule, and turnover documents.
Complete payroll and government updates. Company A reports the separation, while Company B reports the employee as newly employed under its own employer registration.
Collect separation documents from Company A. Obtain the Certificate of Employment, final-pay computation, BIR Form 2316, clearance confirmation, and statement of transferred or paid benefits.
Check the first two payroll cycles. Verify salary, tax withholding, SSS, PhilHealth, Pag-IBIG, HMO activation, leave balances, and recognized service date.

Documents, Deadlines, and Practical Timelines

Document or action	Responsible party	Practical or legal timing
Transfer proposal or term sheet	Both companies	Before asking the employee to resign
Tripartite transfer agreement	Employee and both companies	Before or on the transition date
New employment contract	Company B and employee	Before resignation becomes irrevocable
Resignation notice, if used	Employee	Normally at least one month before effectivity unless waived
Final pay	Company A	Generally within 30 calendar days from separation, unless a more favorable policy or agreement applies
Certificate of Employment	Company A	Within three days from the employee’s request
BIR Form 2316	Company A	Upon the last payment of compensation or within the applicable BIR period
PhilHealth new-employee reporting	Company B	Generally within 30 days from assumption of duty
Government contribution verification	Employee and Company B	Check after the first or second payroll posting
Foreign-worker permit and visa changes	Company B and foreign employee	Before employment under the new legal entity begins

DOLE Labor Advisory No. 06, Series of 2020 provides the general 30-day period for final pay and the three-day period for issuing a requested Certificate of Employment. DOLE reiterated these timelines in January 2026. (Department of Labor and Employment)

PhilHealth requires employers to report newly hired employees generally within 30 days from assumption of duty and to report separated employees within the prescribed period. (PhilHealth)

For SSS, each corporation reports the employment under its own employer account. The employee should retain the same personal SSS number, but the employer reporting and contribution records must reflect the transition correctly. (Social Security System)

BIR and Payroll Consequences

Company A should prepare the employee’s BIR Form 2316 covering compensation and taxes withheld up to the separation date. Company B will issue a separate BIR Form 2316 for compensation it pays during the same calendar year. BIR rules require an employer to furnish Form 2316 upon termination of employment or within the regular annual deadline, as applicable. (Bureau of Internal Revenue)

An employee who receives compensation successively from two employers during one taxable year may need to file an annual income tax return personally rather than rely on substituted filing. The two Forms 2316 should therefore be kept together. Current BIR guidance expressly recognizes employees who earn compensation from two or more employers, whether concurrently or successively.

The payroll teams should also agree on who will handle:

Annualized withholding adjustments;
Prorated 13th-month pay;
Taxable and non-taxable benefits;
De minimis benefits;
Bonuses earned before but paid after the transfer; and
Any tax refund or deficiency caused by the midyear change of employer.

Special Rules for Foreign Employees

A foreign employee should not assume that an Alien Employment Permit or 9(g) pre-arranged employment visa issued for Company A automatically allows employment with Company B.

Under DOLE Department Order No. 248, Series of 2025, as supplemented by Department Order No. 248-A, an Alien Employment Permit is issued in relation to a particular Philippine employer and approved position. A change of legal employer may require a new application or other formal action before the foreign national begins working for the sister company. (Calabarzon Dole)

A 9(g) visa is also based on a qualifying employment arrangement and employer sponsorship. Resignation or termination may require visa downgrading, cancellation of the existing ACR I-Card, and a new application under the succeeding employer. (Bureau of Immigration Philippines)

Foreign employees should settle the following before the transfer date:

AEP validity and employer details;
9(g) visa status;
ACR I-Card cancellation or amendment;
Downgrading requirements, when applicable;
New employer sponsorship;
Dependents’ visa status; and
Whether authenticated or apostilled foreign documents are required for the new filing.

The employee should not perform services for Company B while relying only on a permit naming Company A unless DOLE and the Bureau of Immigration have confirmed that the arrangement is permitted.

Common Problems in Sister-Company Transfers

“Nothing changes except the company name”

This is often inaccurate when the SEC-registered employer changes. Even when the desk, manager, job, and salary remain the same, the employee may have a new employment contract, new benefit rules, a new retirement plan, and a different party legally responsible for wages.

The employee is told to resign immediately

Urgency usually benefits the companies more than the employee. Payroll cut-offs, restructuring deadlines, or internal accounting concerns do not justify asking an employee to give up accrued rights without final written terms.

Prior service is recognized only “for seniority”

That wording may not cover retirement, separation pay, leave entitlement, bonuses, or service awards. The agreement should identify every benefit for which prior service counts.

Company B imposes probationary status

Because Company B is a separate employer, it may argue that the employee is newly hired. The employee should negotiate express regular status, particularly where the position and duties remain substantially the same.

The old employer pays final pay but no separation pay

This can be legally consistent with a voluntary resignation. Separation pay is generally not due merely because the employee moved to a sister company. It must arise from law, contract, a collective bargaining agreement, company practice, or the negotiated transfer package. (Supreme Court E-Library)

A broad quitclaim is required before the new contract is released

This places the employee in a weak position. The new contract and transfer terms should be final before any waiver is signed. The final-pay computation should also be itemized.

The companies say they are “one and the same”

Related corporations are not automatically treated as one employer. Courts may disregard separate corporate personalities when the corporate structure is used to defeat public convenience, justify a wrong, perpetrate fraud, or evade legal obligations. This remedy is exceptional and requires evidence; common ownership alone is normally insufficient. (Supreme Court E-Library)

What Can an Employee Do if the Transfer Becomes Disputed?

Keep copies of:

Employment contracts with both companies;
The transfer proposal and agreement;
Resignation letter;
Emails, messages, and meeting notes;
Payslips and BIR Forms 2316;
Company policies and retirement-plan rules;
Leave and benefit statements;
SSS, PhilHealth, and Pag-IBIG contribution records;
Certificates of Employment; and
Final-pay and quitclaim documents.

An employee may file a Request for Assistance through DOLE’s Single Entry Approach, or SEnA. It is a mandatory conciliation-mediation process intended to resolve labor disputes within a 30-day period before they become full cases. Unresolved illegal-dismissal and money claims may proceed to the appropriate National Labor Relations Commission Regional Arbitration Branch. (Sena Webb App)

The legal characterization will depend on what actually happened—not merely on the title of the document. A document labeled “voluntary resignation” may still be examined for coercion or constructive dismissal, while a document labeled “transfer” may in reality establish a new employment relationship.

Frequently Asked Questions

Can my employer transfer me to a sister company without my consent?

Generally, not as a permanent change of legal employer. A sister company is normally a separate juridical entity. The employee must consent to employment by the new corporation. An employer’s management prerogative to transfer personnel is strongest when the legal employer remains unchanged.

Do I need to resign before transferring to a sister company?

Not necessarily. The parties may use a tripartite transfer or employment-assumption agreement. When resignation is required for administrative purposes, it should be conditional on the simultaneous effectivity of the signed new contract and the preservation of agreed benefits.

Will my years of service automatically carry over?

No. Prior service does not automatically carry over between separately incorporated employers. The transfer agreement should expressly state the original recognized service date and identify every benefit for which prior service will count.

Can the sister company put me on probation again?

It may try to do so because it is a new employer. The employee can negotiate regular status from the first day, particularly when the job, duties, workplace, and corporate group remain substantially unchanged.

Am I entitled to separation pay if I resign to join the sister company?

Usually not, unless separation pay is provided by contract, CBA, established company policy, or the transfer arrangement. A voluntary resignation by itself normally does not create a right to separation pay.

Should I receive final pay from the old company?

Yes. Company A should account for unpaid wages, prorated 13th-month pay when applicable, convertible leave, reimbursements, commissions, tax adjustments, and other amounts due under law or company policy.

Can the companies simply continue using my old hiring date?

They can contractually recognize it. The agreement should explain whether the date applies to seniority, leave, retirement, separation pay, service awards, bonuses, and notice periods rather than using a general statement that may later be interpreted narrowly.

Does a transfer agreement need to be notarized?

Notarization is not ordinarily what creates the employment relationship, but it can strengthen proof of execution and identity. Companies may also require notarization because the agreement includes waivers, corporate undertakings, immigration documents, or authority certificates.

What happens to my SSS, PhilHealth, and Pag-IBIG numbers?

The employee keeps the same personal membership numbers. The old employer must properly report the separation, while the new employer must report and remit contributions under its own employer account. The employee should verify actual contribution postings after the transition.

What if I already signed a resignation but the sister company changed the offer?

The result depends on the resignation letter, written promises, surrounding communications, whether the resignation was conditional, and whether it has already become effective. Preserve all evidence showing that the resignation was given only because of the promised transfer package.

Key Takeaways

Sister companies are usually separate legal employers even when they share owners, managers, offices, or branding.
A permanent move to another corporation generally requires the employee’s informed consent.
A bare resignation followed by rehire may reset seniority, regular status, retirement service, leave, and other benefits.
A three-party transfer or assumption agreement is usually safer because it can preserve rights and allocate liabilities clearly.
The agreement should expressly cover the recognized hiring date, regular status, compensation, leave, retirement, separation benefits, taxes, government contributions, and immigration requirements.
Never rely solely on verbal assurances that “all benefits will continue.”
The new employment contract and transfer terms should be signed before the resignation becomes effective.
Foreign employees must separately check AEP, 9(g) visa, ACR I-Card, and employer-sponsorship requirements before working for the new company.
