"Afterhours" isn't the thing. Having the flexibility to work the hours when you feel, and are, productive is what benefits everyone.
Put in 11-hours today, very unusual. But I was having a good time and jamming out. Kinda wanted to work more! But I was getting burnt, making mistakes, everyone else gone home, didn't want to annoy them with messages.
Tomorrow? Hell, I may fuck off the rest of the week until vacation starts. I'll have Slack on, check my calendar and email, bet money I sleep in till 9:30 or 10, catch up on my novel.
As to PTO? I can almost take every Friday. Hell, HR came in last year and said, "Taking a 3-day weekend is essential to your mental health and productivity. You now get a Monday or Friday off, every month, on top of PTO. This is mandatory, do not test us."
Let us do the fuck we want. Given clear management expectations and making it happen? No one cares the hours you keep. Not getting the job done? Fired. FFS, we're all adults here.
My new boss, "I do not believe in micromanaging. If you find me micromanaging, I'm already hunting your replacement."
