What does your contract say? With this back to work bullshit I made sure my contract explicitly said I was remote.
Doesn't mean they won't change their mind but maybe I'll get severance instead of fired for cause of they have a back to the office push.
I was at a subsidiary of a very large company and had work slack, email, and all my code on my phone, without even the thing that lets them remote wipe your phone.
It has to do with culture and willingness to put in the effort by the security organization
