Can I request written documentation of why I was fired?
Question Details: I was fired with no warning for "being creepy towards female workers" and "working so many hours that other workers were creeped out that I was always working". I believe I was fired for working too many hours since I told co-workers that I was working as many hours as I could so I could make $900 on my paycheck at the end of 3 weeks. Before I was fired today, I overheard one of the managers saying, "If he thinks that he's going to work that many hours and get paid" and then they stopped talking when I was close. Can I go back to my job right now and request any documentation they have on me (write-ups and such)?
You can request, but they don't have to provide unless you were sue them for wrongful termination and the lawsuit use the mechanisms of "discovery" (e.g. document production requests to it). Employment in this nation is "employment at will"; the employer does not need to justify or support its termination decisions outside of litigation.
Bear in mind that an employer may terminate you if it feels you are trying to accumulate too many hours--that is certainly unfair, but it is legal, since under employment at will, there is no right to or guaranty of a job and you may be terminated at any time for any reason. Similarly, if coworkers complain about you, even if their complaints are unfair, you may be terminated.
