Re: a Wrongful Termination
Something else you might consider:
Understand that although, while you may not view the [whatever] as not inappropriate, somebody else might. If somebody else is exposed to the photos, jokes, etc. and they see it as inappropriate, it can easily be a basis for sexual harassment claim. The employer MUST rectify the situation. While termination is extreme and not the only remedy available, it is fast, certain, and obvious.
Of course, the person above you may have simply thrown you under the bus to save his own ass. That's not illegal either.
I am not an attorney and any advice is not to be construed as legal advice. You might even want to ignore my advice. Actually, there are plenty of real attorneys that you might want to ignore as well.
