Really depends on if one thinks his being fired to be the appropriate response. If (like you seem to think) it is, then sure, there is no issue about workers' rights here. If you tend to believe him that this was an honest mistake, or even just that there's sufficient doubt, then the conclusion would probably be that he shouldn't have been fired, and his having been fired becomes a question of "how could this happen". And to this the (my) answer is "insufficient workers' rights, allowing a company to take an easy way out at the cost of an individual".
