In Academia, it's not too uncommon for people to take extended sabbaticals to focus on a project without being distracted with work nonsense, but I haven't really heard of any company doing that in the US.
I would love to take around a month every year just to focus on a purely technical problem instead of focussing 20% of my time in technical stuff, and 80% of my time going through bureaucratic hoops that seemingly have no reason to exist outside of creating a job for the bureaucrats.
I have an OK job overall, but there's just a metric ton of approvals and paperwork that I end up having to do to actually write code, and as a result I get burnt out fairly often.
