I've been working my butt off for my current manager for 3 years, always volunteering to take on extra work, working for free just to get stuff done, helping her with things she struggles with, etc. She started after me and came from a totally different field, so she needed a lot of help.
This week I got sick, possibly covid. I have barely slept in days, I'm in pain, I and let her know I would have to work remotely.
Instead of showing any sympathy for my situation, she gets mad at me, like how dare I abandon her during a busy week and gives me an attitude like I'm worthless. I've saved this person's ass more times than I could remember, and the second I need something in return, she considers me trash and makes no secret of it.
Just remember folks: they may act like they're your friends, but they don't give a fuck. You're only as good to them as what you've done for them lately. Look out for yourselves, not for corporations.
