What do you mean by "forced"?
Did they threaten to fire you if you didn't carry on working?
If it ever comes to court it might just be your word against theirs.
For example my neice was bullied by her boss at work so she quit and took him to court, but she lost the case because she couldn't prove he bullied her.
I once got the 6-man reception staff at a tower block fired because I secretly recorded a conversation I had with them..
So if I were you I'd try to get some kind of proof against your bosses that they threatened to fire you.
For example get them to admit it in a letter or a secretly-filmed video conversation with them.
