even if he is just trying to recoup unpaid wages? there are fairly strict laws in this country surrounding that. I understand how being in litigation with a previous employer would look bad to a potential new one but I'd like to believe there is at least a little leeway there.
Yes. It will hurt his employment status. Companies don't want to hire employees who are suing former employers. Not always fair, but it's because there are a TON of people who frivolously sue their employers.
I strongly disagree. He should absolutely go after his lost wages by any means possible and it will do nothing to affect his employment status. There's no reason for him to inform future prospective employers of this and there's no way they will find out. As a hiring manager I would have absolutely no problem hiring someone who had to sue a previous employer for lost wages and I doubt anyone else would. If there's a long pattern of suing employers in various situations that's obviously different.
