In the tech sector, IBM announced their mandate last week, justifying it by claiming as they have some contracts with federal agencies (for servers and services) that means they're Federal Contractors and thus required to be 100% vaxxed. Get the jab by December 8th or you're put on "unpaid leave" and/or "have badge access revoked."
The latter is a fancy way of saying they'll disable your computer accounts as well as access to IBM buildings. The former is a neat trick, as Unpaid Leave means they don't have to fire you and thus don't have to risk a wrongful termination lawsuit; they just leave you hanging forever until you give up and quit for a new job or get the jab.
Oh, and no exemption process in place according to my sources. So if you're religious and object to the idea of using a vaccine made out of fetal tissue remains of murdered babies, you can just get fucked, Daddy IBM thinks your silly little beliefs are quaint but they will make your medical decisions for you, thank you very much.
