I’m so sorry they did this to you. My blood is boiling! What kind of soulless monster makes these kind of decisions. It not only puts the screws to you but also to the company because they lose your talent and expertise while ki-ling morale. I have to assume you don’t have performance issues because you would have been on their radar in one of the prior layoffs. They always throw in some poor performers and young employees so they can claim it had nothing to do with salary, age or pension.
Get yourself a decent lawyer and don’t sign anything. There were people who were targeted in 2019 because of exactly the same thing and some of them sued. Ford was fighting it until someone got their hands on emails proving Ford targeted people who would save them the most money long term. Ford settled out of court. I would hope their proven track record of being despicable would help you in court. They are also ignorant and arrogant (bad combination). They already settled because of this practice yet they did it again.
