Why "endo" is illegal, even though fixed-term contracts aren't

Contractualization under Philippine labor law — the line between legitimate fixed-term work and unlawful "5-5-5" hiring, and what it means for workers and employers

"Endo," short for "end of contract," is one of the most talked-about labor issues in the Philippines — and one of the most misunderstood. Many assume any short-term or contractual job is automatically illegal. It isn't. Philippine law allows genuine fixed-term, project, and seasonal employment. What the law prohibits is using short contracts as a scheme to keep workers perpetually temporary and deny them the security of tenure they're entitled to once their work meets the legal test for regularization.

What "endo" actually means

Endo, sometimes called "5-5-5," describes the practice of hiring a worker on a short contract — commonly five months — letting it lapse just before the employee would otherwise qualify for regular status, and then rehiring them under a new short-term contract, sometimes after a brief gap designed to look like a break in service. The cycle repeats indefinitely, so the worker never accumulates the tenure the law is designed to protect, even while doing the same job, under the same supervision, for years.

The legal foundation: regular employment and probation

Article 295 of the Labor Code defines regular employment: a worker is deemed regular where the work performed is usually necessary or desirable to the employer's usual business or trade, regardless of any written agreement stating otherwise. This is often called the "necessary or desirable" test, and it looks past the label on the contract to the actual nature of the work.

Article 296 sets a hard cap on probationary employment at six months, after which a worker who continues working must be considered regular, complete with security of tenure and the standard package of statutory benefits — SSS, PhilHealth, Pag-IBIG, paid leave, and protection from dismissal without just or authorized cause. Endo schemes exist specifically to keep workers just short of that six-month mark, contract after contract.

Fixed-term contracts are not automatically illegal

Philippine law does recognize legitimate fixed-term employment, seasonal work, and project-based engagements. The Supreme Court's foundational case on this, Brent School, Inc. v. Zamora, held that a fixed-term contract is valid where the term was knowingly and voluntarily agreed upon by the parties, without any vitiation of consent, and where the employer and employee dealt with each other on relatively equal terms without one exercising moral dominance over the other.

The distinction that matters is intent and substance, not the paperwork. A construction worker hired for the duration of a specific project, or a retail worker hired for a defined holiday season, can lawfully be a fixed-term or project employee. A customer service agent doing the exact same core, year-round work as regular staff, but kept on a repeating five-month cycle specifically to avoid regularization, is not.

Labor-only contracting: the other half of the problem

Endo is closely tied to a second practice: labor-only contracting, where a manpower agency merely recruits and supplies workers to a company without real capital, tools, or control over how the work is done — functioning as a pass-through rather than an independent contractor. Department Order No. 174, Series of 2017, which implements Articles 106 to 109 of the Labor Code, expressly prohibits this arrangement and specifically bars "repeated hiring under contracts of short duration... designed to circumvent the employee's right to security of tenure."

Where labor-only contracting is found, the law treats the principal company — not just the agency — as the real employer, responsible for regularizing the affected workers and liable for their statutory benefits. DOLE is authorized to order the closure of a labor-only contractor and impose administrative fines, in addition to ordering regularization of the workers involved.

What "illegal contractualization" costs an employer

When DOLE or the NLRC finds that a series of short-term contracts was really a scheme to avoid regularization, the consequences typically include:

• Regularization of the affected workers, retroactive to when they should have qualified.
• Payment of unpaid statutory benefits and mandatory contributions for the period they were wrongly kept as contractual.
• Backwages and, where an employee was dismissed to avoid regularization, liability for illegal dismissal.
• Administrative fines and, for labor-only contractors, closure of the contracting arrangement itself.

Where the law stands today

There is currently no single statute that bans "endo" by name. Enforcement instead rests on Articles 106 to 109, 295, and 296 of the Labor Code, together with DOLE's implementing rules under Department Order No. 174. Various versions of a "Security of Tenure" bill, aimed at tightening the definition of labor-only contracting and closing the loopholes that allow endo to persist, have been filed and refiled across several Congresses — passing one chamber at different points, but not yet enacted into law as of this writing. Until dedicated legislation passes, disputes over whether a hiring pattern crosses the line into illegal contractualization continue to be resolved case by case, based on the "necessary or desirable" test and the existing rules against labor-only contracting.

Practical guidance

For employers: A fixed-term, project, or seasonal arrangement needs to reflect the actual nature of the work, not a strategy to avoid regularization. If a role is genuinely part of year-round core operations, structuring it as a repeating short-term contract is a legal risk, not a workaround. Where third-party manpower agencies are used, verify that the arrangement meets the legitimate contracting standards under DOLE Department Order No. 174 — real capital, real equipment, and real control over the work — rather than functioning as a mere labor pass-through.

For workers: Keep every contract, payslip, and correspondence about your employment status. If your contract keeps ending and restarting just before the six-month mark, while your actual work and duties stay the same, that pattern itself is evidence. DOLE's Single Entry Approach (SEnA) offers a free, faster first step before filing a formal case, and a labor lawyer can help assess whether your situation meets the legal test for regularization.

The bigger picture

The tension at the heart of the endo debate is not between having contracts and not having them — it's between genuine flexibility for seasonal or project-based work, and using short-term paperwork to strip workers of rights the Constitution and the Labor Code say they're entitled to once their work becomes part of the ordinary, ongoing business of the company that employs them.
