-Find another job.
-Get an Attorney.
-Call the ACLU. (American Civil Liberties Union). But this is for mainly "discrimination" violations.
-Document everything.
-Tell HR.
Those are some of the things he can do.
BUT... the problem is: even if you get legal help and have documentation... it all boils down to this:
1) his supervisor and others are lying and playing dumb about it.
2) thus even if you have documentation... he cannot corroborate the allegations or have witnesses or testimony of others who will back him up. Because they probably don't want to get into trouble either.
3) hence, he will be, getting this bad treatment, still.
4) Hence, no one will help or tell the truth or say, that this is happening.
And thus, your Husband will look like he has no basis to stand on.
5) and the bottom line is also, he needs to have PROOF of these allegations. Even if it is true... you need proof, to make a legal case of it.
Hearsay, will not help.
And, everyone is lying about it and denying it... when your Husband tries to get help or report it.
It is very hard... to prove allegations like this.
And it needs to fall into discrimination parameters... for it to be legally sound, in pursuing it and PROVING it, even if the ACLU gets involved or tries to investigate for your Husband.
This is really sad, yes.
He can keep trying.... it is terrible what they are doing.
BUT your Husband has to be able... to PROVE it.
And with everyone lying about it and denying it... that will be hard to do.
And then it will only be... his word against theirs.
Cases like that... are very hard to prove.
And, in most States, employment is "at will."
Obviously, everyone (his Supervisor and the Union Chairman) are in cahoots together.. since they are both, lying and denying that they said that. And ignoring the situation is merely playing dumb.
When people lie, it is very hard to prove a case, unless your Husband has PROOF, this is happening and documentation etc. or people who will back him up that this is happening.
