Having worked at a nonprofit that recently sold its tech arm to a corporation, some anecdata:

* The workload is indeed much lighter as a corporate employee. I have rarely had to work more than 8 hours in a day, and have not yet had to work all night on anything. They pay reliably; I have not had to delay getting a paycheck or been asked to skip one because money was tight. Indeed, they really want me to let them buy me books and pay for me to take classes.

* There was much less bullshit as a non-profit. As a non-profit, so long as the tasks that needed to be done got done, no one cared if you wanted to start work at midnight and sleep through business hours, and "no" was an acceptable answer to invitations to meetings; "fuck that" was an acceptable response to bad ideas, no matter whose bad ideas they were. No one was required to humiliate themselves with mandatory team-building ritual things. While it was rare to have nothing to do, I never felt obliged to pretend to be busy when I wasn't. No one gave the impression they got some kind of sexual thrill out of being able to declare things "mandatory." Very little was mandatory, other than the work. There was no paperwork other than opening and closing tickets.

I would have preferred to keep the heavier workload and occasionally unreliable pay and avoided the other stuff.
