As for the, "if you're clocked in, you should be working," that would mean in-office employees are working 100% of the time they're clocked in. Have them prove that this is the case.
Then look at productivity during the pandemic vs now and let then explain how WFH hampered those numbers.
Just a ridiculous mindset by boomers who should have retired a decade ago.
I thought in general it was widely agreed upon at this point WFH is at-least a 10% drop in productivity. Stanford has been doing plenty of research in this area. The argument in favor of WFH has for the most part moved on to now cost savings from not having offices lets you hire more people to make up for the loss in productivity.

I wonder if they covered that people working from home may get sick less and work longer hours.
Ye gods, I can concentrate better at home than I can in an open floorplan office lol :D
