I wanted opinions from other lawyers.
Money is not what we are after. However if filing a harassment lawsuit leads to a monetary award. So be it.
We want this manager gone. Everyone is tired of being harassed. And yes we have a case due to several of the people being harassed are women and in the "protected" group.
Thanks for all your advice.
Having read all the other replies, I'm sure I'm spittin' into the wind but here goes...
Jason, you and your co-workers do not have any kind of lawsuit to bring against the company because the boss is a jerk. There simply is no legal means by which you can force your employer to fire this guy.
What you describe does not constitute a hostile work environment in the law nor is the boss being a bully prohibited in Illinois, any other State, or under federal law. Nothing you describe consitutes any form of prohibited discrimination. Being a jerk towards everybody (male/female, white/hispanic/black, young/old, Christian/Jewish/Muslim) is completely legal.
Since you're convinced that you have the basis of a lawsuit, then please spend several hundred dollars and have an employment law attorney tell you the same thing everybody here has explained repeatedly for free. Whatever attorney you claim to have already spoken with clearly knows nothing about employment law.
