I'm used to small, get-things-done environments (startups, small dev shops).
Transitioning to working within a much more "corporate" environment (not that the actual dev team is any bigger) I struggled with the endless gatekeeping and bureaucracy because it was impeding us ... getting stuff /done/.
Once you realise they're not optimising for that goal, I feel less frustrated and have scaled back my efforts accordingly.
Want to do everything via PR, and have andless code-janitoring stylistic bollox ? Fine, I'll do that - but I'm not going to chase you to close it.
Want to spend hours in planning guff and pointless retrospective naval-gazing? Great, I can join the call on mute and get on with something else.
About 10-15 hours actual work per week is fine. "Office Space" is just as true today as it was when it was filmed.
