I was just recently laid off for doing that for several years at my last job. I wasn’t “being a team player” and I “do great work, but I could do more” and my “attitude was affecting the team negatively” (read: your enlightening other employees to the fact we are taking advantage of them). Never mind the fact they fired my assistant 3 years ago and never rehired anyone so i was doing two jobs the entire time. Or the fact during my time there i improved a core function of the job by over 20% and saved the company 10s of thousands a year. No, i needed to do more for free. Fuck every employer who operates this way. /rant
