Under Philippine labor law, the question of whether an employer may issue a Notice of Non-Regularization after an employee has served five months of probationary employment is governed primarily by the Labor Code of the Philippines and its implementing rules. The short answer is yes, provided the employer complies with the strict requirements for valid probationary employment. Such a notice, when properly issued before the expiration of the six-month probationary period, serves as formal communication that the employee has not met the standards for regularization and that the employment relationship will end upon the conclusion of the probationary term. This mechanism is distinct from a regular employee’s dismissal and rests on the employer’s prerogative to assess fitness for permanent status.

The Legal Nature of Probationary Employment

Probationary employment is a legally recognized pre-regularization phase designed to allow the employer to evaluate the employee’s qualifications, skills, and suitability for the job. Article 281 of the Labor Code expressly provides that probationary employment “shall not exceed six (6) months from the date the employee started working, unless it is covered by an apprenticeship agreement stipulating a longer period.” The law further states that an employee allowed to work after the probationary period “shall be considered a regular employee.”

This six-month ceiling is not a mere guideline; it is a mandatory limit. Any extension beyond six months without a valid apprenticeship or learnership agreement automatically converts the employee to regular status by operation of law. The probationary period begins on the first day of actual service, and the counting of months follows the calendar, not the number of working days.

For the probationary arrangement to be valid from the outset, three essential requisites must concur:

The employee must be informed, at the time of engagement, of the reasonable standards by which he or she will be evaluated for regularization.
The standards must be made known to the employee in clear, certain, and unambiguous terms.
The standards must be reasonable and job-related.

Failure to comply with any of these requisites renders the employment regular from the very beginning, even if the parties initially labeled it as probationary. Courts have consistently held that the burden of proving compliance with these requisites rests on the employer.

What Constitutes a Notice of Non-Regularization?

A Notice of Non-Regularization is the employer’s formal written advice to the probationary employee that he or she has not qualified for permanent or regular status. It is, in legal effect, a notice of termination of the probationary contract upon the expiration of the agreed period. Unlike the dismissal of a regular employee—which requires just or authorized cause under Articles 297, 298, or 299 and the twin-notice rule—the termination of a probationary employee is anchored on the employee’s failure to meet the previously communicated standards of performance.

The notice must contain:

A clear statement that the employee did not meet the pre-established standards for regularization.
A summary of the specific areas or metrics where the employee fell short.
The effective date of separation, which must coincide with or immediately follow the last day of the probationary period.
A reminder of the employee’s right to due process if the non-regularization is anchored on any act that could also constitute a just cause under Article 297.

Issuance of the notice after five months is perfectly lawful because five months falls well within the maximum six-month probationary window. The law does not impose a minimum service period before non-regularization can be effected; the employer may decide as early as the first month or as late as the last day of the sixth month, provided the standards were made known at the start and the evaluation is fair and objective.

Timing and Procedural Requirements

The critical temporal requirement is that the notice must be served before the probationary period expires. Once the sixth month ends without any notice of non-regularization, the employee attains regular status automatically. Philippine jurisprudence has repeatedly affirmed that mere silence or inaction by the employer at the end of the probationary period equates to regularization.

Employers often issue the notice during the fifth or early sixth month to allow sufficient time for administrative processing and to afford the employee an opportunity to seek other employment. There is no statutory minimum advance notice period for probationary non-regularization (unlike the 30-day notice required for certain authorized causes affecting regular employees). However, the notice must be given with enough lead time to prevent the employee from rendering service beyond the probationary term without regularization.

If the employer discovers acts or omissions that also constitute just causes under Article 297 (e.g., serious misconduct, willful disobedience, gross neglect), the employer may opt to dismiss the probationary employee immediately rather than wait until the end of the probationary period. In such cases, the full twin-notice requirement and due process under the Omnibus Rules on Illegal Dismissal must be observed.

Rights and Obligations of the Parties

Employer’s Rights and Obligations

The employer retains the prerogative to set reasonable performance standards and to decide, based on those standards, whether to regularize the employee.
The employer must keep adequate documentation of the evaluation process, including performance appraisals, counseling records, and written feedback given to the employee during the probationary period.
The employer is obligated to pay the probationary employee all wages, benefits, and 13th-month pay proportionate to the period actually served.
Separation pay is generally not required for a valid non-regularization unless company policy or a collective bargaining agreement provides otherwise.

Employee’s Rights

The probationary employee enjoys security of tenure during the probationary period and cannot be terminated arbitrarily.
The employee has the right to be evaluated fairly and objectively against the standards that were disclosed at the time of hiring.
If the employee believes the non-regularization was made in bad faith, without basis, or without prior disclosure of standards, he or she may file a complaint for illegal dismissal with the National Labor Relations Commission (NLRC).
The employee is entitled to due process if the ground cited also amounts to a just cause for dismissal.

Common Legal Issues and Pitfalls

Several recurring issues arise in non-regularization cases:

Lack of Prior Disclosure of Standards – This is the most frequent ground for declaring non-regularization illegal. Courts have ruled that vague or after-the-fact standards cannot justify termination.
Automatic Regularization by Operation of Law – If the employer allows the employee to continue working even one day after the sixth month without a prior notice of non-regularization, the employee becomes regular. Subsequent attempts to issue a belated notice are void.
Extension of Probationary Period – Any agreement to extend the probation beyond six months is generally invalid and will result in regularization unless the extension falls under a lawful apprenticeship or learnership program duly approved by the Technical Education and Skills Development Authority (TESDA).
Bad-Faith Non-Regularization – If the employer’s real motive is to avoid granting regular status benefits (such as security of tenure or higher compensation), courts will pierce the probationary label and declare the dismissal illegal.
Multiple Probationary Periods – An employer cannot repeatedly hire the same employee on successive probationary contracts for the same position; doing so is a circumvention of the law and will convert the employee to regular status.

Remedies Available to the Aggrieved Employee

Should an employee contest the Notice of Non-Regularization, the following remedies are available:

Complaint for Illegal Dismissal – Filed before the NLRC within four years from the date of dismissal.
Reinstatement with Full Back Wages – The usual relief if the non-regularization is declared illegal.
Damages and Attorney’s Fees – Moral and exemplary damages may be awarded when the employer acted in bad faith.

The burden of proof lies with the employer to show that (a) the standards were disclosed, (b) the employee failed to meet them, and (c) the notice was timely served.

Conclusion

An employer in the Philippines may lawfully issue a Notice of Non-Regularization after five months of probationary service, as this remains comfortably within the six-month statutory limit. The power to do so, however, is not absolute. It is conditioned upon strict compliance with the requirements of prior disclosure of reasonable standards, fair evaluation, and timely notice before the probationary period expires. Both employers and employees are well-advised to maintain clear documentation and to understand that probationary employment, while flexible, is heavily regulated to prevent abuse and to uphold the constitutional mandate of security of tenure. Any deviation from these legal safeguards may transform what appears to be a simple non-regularization into an illegal dismissal, with corresponding liabilities for the employer.
