When I did WFH my boss insisted that because I didn't have to commute I should have all my tools up before my shift even starts.
I didn't last very long.
This same company got sued up the ass when we were in office for trying to say we needed to have all our tools up before clocking in. But somehow WFH made it ok.
Any kind of work, should be after you clock in. Getting equipment, tools, software started etc. is work. Companies trying to deny that should be reported.
Pre-shift prep time is paid. At my last shift job, we were expected to be there and ready before the shift started, but we also got paid for that time.
