In the Philippine legal landscape, the intersection of labor productivity and reproductive health is governed by a strict framework designed to prevent discrimination. When an employer decides not to regularize a pregnant probationary employee specifically citing performance issues, they must navigate the delicate balance between management prerogative and the protective mantle of the Magna Carta of Women (Republic Act No. 9710) and the Labor Code.

1. The Principle of Probationary Employment

Under Article 281 of the Labor Code, probationary employment shall not exceed six months. For an employee to be regularized, they must meet the reasonable standards made known by the employer at the time of engagement.

If the employee fails to qualify as a regular employee in accordance with these standards, the employer has the right to terminate the services. This is a recognized Management Prerogative.

2. The Burden of Proof: Performance vs. Pregnancy

The primary legal risk in this scenario is a claim of Illegal Dismissal based on gender discrimination. Philippine courts generally view the dismissal of a pregnant woman with heightened scrutiny.

Valid Non-Regularization

To successfully defend a non-regularization based on performance, the employer must prove:

Established Standards: The performance criteria were clearly communicated to the employee at the start of the probation.
Due Process: The employee was informed of her poor performance through evaluations or notices during the probationary period.
Documentation: There is objective evidence (e.g., scorecards, KPIs, performance reviews) showing that the failure to meet standards is unrelated to the pregnancy.

The "Prohibited Act"

Under Article 135 (now Article 133) of the Labor Code, it is unlawful for an employer to discharge a woman on account of her pregnancy. If the "performance issues" are deemed a mere pretext to avoid the costs of maternity leave or the perceived "burden" of a pregnant worker, the dismissal is void.

3. Statutory Protections for Pregnant Workers

The Philippine government provides robust protection through several key laws:

RA 9710 (Magna Carta of Women): Prohibits discrimination against women. Specifically, Section 35 emphasizes that the State shall ensure that women are not dismissed from work due to pregnancy or for taking maternity leave.
RA 11210 (105-Day Expanded Maternity Leave Law): This law grants 105 days of paid leave. Termination to circumvent this benefit is a direct violation of the law.
DOLE Advisory No. 01, Series of 2024: Reiteration of the protection of workers against pregnancy-related discrimination.

4. Consequences of Illegal Dismissal

If the National Labor Relations Commission (NLRC) finds that the performance issues were fabricated or that the pregnancy was the "proximate cause" of the non-regularization, the employer faces:

Reinstatement: The employee must be returned to her position without loss of seniority rights.
Full Backwages: Payment of the salary the employee would have earned from the time of dismissal until actual reinstatement, including 13th-month pay and other benefits.
Moral and Exemplary Damages: Awarded if the dismissal was done in a wanton or oppressive manner.
Attorney’s Fees: Generally 10% of the total monetary award.

5. Key Jurisprudence and Interpretation

The Supreme Court of the Philippines has often ruled that while the employer has the right to hire and fire, this is limited by the constitutional protection to labor. In cases involving pregnant probationary employees, the timing of the dismissal is often a "red flag." If an employee has had satisfactory reviews until the pregnancy was disclosed, the shift to "performance issues" is often viewed as a badge of bad faith.

Note: Even if the performance issues are real, the employer must ensure that the "reasonable standards" were not rendered impossible to meet because of the pregnancy (e.g., requiring a pregnant woman to lift heavy objects when her job description didn't originally require it).

Summary of Employer Obligations

To mitigate legal risks, an employer must ensure that:

Performance evaluations are periodic and objective.
The decision to not regularize is supported by a paper trail that predates the pregnancy or is clearly independent of it.
The employee is given a chance to improve (though not strictly required for probationary employees, it serves as evidence of good faith).
