Short answer. No. Article 301 is the Labor Code's separability clause: if a court holds any single provision, or its application to a particular person or situation, invalid, only that part falls. The rest of the Code, and that same provision's application to other people or situations, remains fully valid and enforceable.
What the law says
If any provision or part of this Code, or the application thereof to any person or circumstance, is held invalid, the remainder of this code, or the application of such provision or part to other persons or circumstances, shall not be affected thereby.

Why the Labor Code includes this clause
Lawmakers routinely add a separability, or severability, clause to a large statute precisely because a code this size contains hundreds of separate rules on hiring, wages, working hours, termination, and dispute resolution. Without such a clause, a successful challenge to one narrow rule could create uncertainty about whether the entire Code, or even unrelated chapters, remained enforceable. Article 301 removes that risk by design, and the approach is standard drafting practice found across Philippine statutes generally, not something unique to labor law.
What the clause actually protects
Article 301 covers two distinct situations. First, if an entire provision or part of the Code is held invalid, everything else in the Code keeps operating normally. Second, if a provision is valid in general but its application to one particular person or circumstance is struck down, that same provision still applies to everyone else it was written to cover. In practice, this means a challenge aimed at how a clause was applied in one company's or one worker's dispute does not automatically remove that clause from the statute book for anyone else.
How it plays out for workers and employers
Suppose a specific rule inside the Code were successfully challenged as invalid when applied to a narrow set of workers or employers. Article 301 means that outcome does not automatically excuse other employers from following that same rule for their own employees, and it does not throw out unrelated protections such as minimum wage, overtime pay, security of tenure, or the dispute-resolution machinery found elsewhere in the Code. This matters because most workplace disputes turn on a handful of specific articles, and a ruling affecting one of those in isolation leaves the broader framework of employee protections intact.
What it does not do
The clause is a safety net for the rest of the Code, not a shield for the specific provision found invalid; that provision, or that particular application of it, still falls. It also does not freeze the Code in its original form. The Labor Code has been amended, renumbered, and partly superseded many times since 1974, so anyone relying on a single article should confirm it has not since been repealed or replaced by a later law or regulation before treating it as current.
