Even if you are right or lowballed on severance. Nobody is going to sue despite tough talk.
A lawsuit with Imperial will be filled with legal costs as they drag things out every step od the way. They will ignore your lawyer, file things late, challenge procedural issues that don’t matter every step of the way.
With the working notice they have provided and mobility survey, they have done everything to appear reasonable, even if they aren’t.
Likely everyone could be entitled to slightly higher severance than what is offered, but they won’t budge. They are offering just enough that lawyers will tell people its not worth the fight.
You will spend $100,000+ fighting this only for them to marginally increase the offer as a settlement offer. Recouped legal fees if you wi. will be 60% of this at maximum.
The process is the punishment. In the meantime you will have the reputation as a troublemaker in the industry and burn through all your savings to pay the bills.
Your only hope is a class action but you will be lucky if you can find a lawyer willing or able to take it on given the varying circumstances, then the court needs to approve.
If several people sue they will make a motion in court to do case management, where they will fight for the lowest performing, shortest length of service employee to be the lead case.
They have everyone by the short and curlies, and you will all take it.
