Short answer. Yes. Article 92 of the Labor Code lets an employer require rest-day work where the nature of the work requires continuous operations and the stoppage of work may result in irreparable injury or loss to the employer. Operations genuinely designed to run without interruption fall within this ground.

The continuous-operations ground
Article 92 allows rest-day work where the nature of the work requires continuous operations and the stoppage of work may result in irreparable injury or loss to the employer. This ground is tied to the nature of the work itself, not to a one-off event like a disaster or an urgent repair. Some operations are structured to run without stopping, and this is the ground that covers keeping them running through a rest day.
Why 'the nature of the work' is the starting point
The article does not ask whether stopping would merely be inconvenient — it asks whether the work is the kind that requires continuous operations in the first place. That points to processes where an interruption is not simply a delay but a disruption to how the operation functions at all, which is a narrower category than any job an employer would prefer not to pause.
'Irreparable injury or loss' sets a real threshold
The ground further requires that stoppage may result in irreparable injury or loss to the employer. Loss that could be recovered or made up later — lost productivity that can be regained, or a delay that can be absorbed — does not fit this description as cleanly as loss that cannot be undone once the operation is interrupted. The word irreparable is doing real work in this clause.
How this differs from the other listed grounds
Unlike the emergency ground, which responds to a specific disaster, or the urgent-repair ground, which responds to a machinery breakdown, this ground is about the ordinary, built-in character of certain operations — the kind that are simply not designed to stop. Whether a given job qualifies depends on whether stopping it truly threatens irreparable injury or loss, not merely whether uninterrupted operation would be preferable for the employer. The ground applies across industries and does not single out particular sectors; what decides it is the operation's own nature. An employer that requires rest-day work here without meeting both parts of the test — continuous operations and irreparable injury or loss — has not brought itself within Article 92's ground.
