A former colleague who is suing our ex employer for poor treatment and sexual harassment has asked if I would make a statement to the EEOC on his behalf. Is there any way my ex employer could take any action against me for this? If I choose to make a statement, do I have any further obligation to remain involved after that? Lastly, since I agreed to help over an email conversation, if I change my mind, is there any way that I could now be subpoenaed or the like and be legally forced to get involved? Thank you.
