Short answer. No. It is expressly unlawful for an employer to discharge, cut your pay, or discriminate against you in any manner because you filed a wage complaint, started a proceeding, or testified — or are about to testify — in one. Retaliation is a violation in its own right.
What the law says
It shall be unlawful for an employer to refuse to pay or reduce the wages and benefits, discharge or in any manner discriminate against any employee who has filed any complaint or instituted any proceeding under this Title or has testified or is about to testify in such proceedings.

How wide the protection reaches
The provision is drafted broadly on purpose. It bars four things: refusing to pay wages and benefits, reducing them, discharging you, and discriminating against you "in any manner". That last phrase is what makes the rule bite, because retaliation is rarely announced. Being taken off the schedule, shifted to a punishing assignment, stripped of overtime, moved to a distant branch, passed over for a regular slot, or frozen out of a promotion can all amount to discrimination even though nobody used the word dismissal. The protection also covers the witness, not only the complainant — and it reaches an employee who "is about to testify", so an employer cannot lawfully act pre-emptively to stop the testimony.
The link between the complaint and the treatment
What turns an ordinary management decision into a prohibited one is the connection to your complaint. Employers may still discipline for genuine cause, reorganise, and manage the workplace; the article does not make a complainant untouchable. The battleground is therefore causation. Timing is the single most telling piece of evidence — treatment that changes sharply within days or weeks of the complaint being filed or a hearing being set invites a hard look. So does inconsistency: a rule enforced against you alone, a performance record that was clean until the filing, or a reason for dismissal that shifts each time it is explained.
What to preserve, starting today
Documents decide these cases. Keep the complaint itself and proof of when it was filed or when the employer learned of it. Keep payslips from before and after, so a reduction is visible on paper. Save memoranda, chat messages, schedules and duty rosters showing the change in treatment, and note the names of people who witnessed it. If you are told to resign, sign a quitclaim, or accept a transfer because of the case, do not sign on the spot and ask for the instruction in writing. A quitclaim signed under pressure is far harder to unwind than one you simply declined.
Two distinct claims, and their limits
Retaliation usually produces two separate grievances: the underlying money claim for the unpaid wages or benefits, and the illegal dismissal or discrimination claim arising from the reprisal. They are pursued together but stand on their own facts, and abandoning the first does not extinguish the second. Bear in mind that money claims under the Labor Code are subject to a prescriptive period, so delay costs real recovery. Nothing here promises a particular outcome, and it is general information rather than advice — how a case is framed and where it is filed depends on your employment status and the facts.
