The summer Friday thing is, I'm pretty sure, office workers themselves choosing to work longer Monday-Thursday and leaving early on Friday when desirable, then management taking credit for doing it for morale reasons lol. Like it's a very very odd "perk" to remove (unless you're extremely vindictive) because it's at literally no cost, and people are probably not very productive Friday afternoons in July anyway. So much shit since covid has been vindictive management disciplining labor for absolutely no benefit.
