I work in a Global Tech data team. Up until this past week, I've only heard from my manager informally in meetings to come into the office 3 days per week. It's even been said in the past no one is monitoring. No details on what would happen if we didn't. We were just told in email VPN reports are being run and it better show 60% of our week is in office. Even if there's a holiday, you're still expected 60%, or 24 hours per week in office network.
Management is unfortunately not interested in giving employees deliverables and then verifying they actually completed them, regardless where it was completed from. That would require "managing".
Note, everything we do is logged. If they want to get rid of any of us, they have the resources to do so.
