Yes, but it's just one of a multitude of ways someone could cheat at work, including lying flat out about holding degrees (which in most cases isn't even illegal), or simply faking their effort in the job, and not really doing it. If people are going to cheat themselves out of an education, and then cheat at a job... ultimately they will be 'found out' for not doing their job properly. Unless there is absolutely no objective way to evaluate, measure, or observe job performance, in which case the job is probably nonsense anyway and cheating doesn't matter.
