Short answer. Not on the statute's own terms. Article 282 authorizes dismissal for fraud or willful breach by the employee of the trust reposed in him, which describes an actual act of fraud or a deliberate betrayal, not a hunch about one. The ground is defined by the conduct occurring, so suspecting it is not the same as it happening.

What the ground actually describes
Article 282 lists fraud or willful breach by the employee of the trust reposed in him by his employer or duly authorized representative as one of the causes for which an employer may terminate employment. Both words in that phrase point to something that actually happened: fraud is a deceitful act, and a willful breach is one done deliberately, not carelessly or by mistake. The ground is defined by what the employee did, and an employer relying on it is invoking a specific factual claim about the employee's conduct, not a general impression.
What the article leaves unaddressed
Article 282 does not itself set out how an employer must establish that fraud or a willful breach of trust actually took place — it names the cause without describing the process for proving it. That gap matters: the text tells you what has to be true for this ground to exist, but not the mechanics of showing it is true in a particular case. Where the facts are genuinely disputed, that is a question the bare wording of this article does not resolve on its own.
How this cause sits among the others
Article 282 groups this cause with serious misconduct or willful disobedience, gross and habitual neglect, and commission of a crime or offense against the employer or their family. Each of these describes a specific kind of conduct, several qualified by words like "willful" or "habitual" that demand more than a single ambiguous incident or an employer's impression. Reading fraud or willful breach of trust alongside these other grounds reinforces that the article is naming actual conduct, consistently across the list, not a standard the employer merely believes is met.
What this means for you
If your employer's basis is only suspicion, with nothing pointing to an actual dishonest or deliberately disloyal act on your part, that falls short of what Article 282 itself describes as the cause. Gather whatever record exists of what you were actually accused of and when, since the ground your employer invokes has to match a real, specific act of fraud or willful breach of trust — not a feeling that something might be wrong.
