They also want us to prove we're vaccinated which will expose our health information on the cloud in out HR system. I fully intend to fight this and I've emailed American Frontline Doctors. If my department manager isn't willing to fight this I'll be forwarding AFDs documentation. At worse, threaten resignation.
I've worked here for 4 years and I know they can't afford to train someone else with the workload we do. And since I've been in IT nearly all my life I can safely say I can get a job elsewhere with relative ease. (Or perhaps collect unemployment and milk Illinois while I build my own business up, we'll see).
Good luck!! Keep us posted! I too live and work in Illinois - so far, we can go maskless if we are vaccinated... or choose not to say.. :) Legally they can't ask about our personal medical information - and I will threaten a lawsuit if they even ask!
