Bosses hate it when their employees have more than one job because secretly (or sometimes not so secretly) they want to own all of your time. Redditor u/AZNM1912 already had a full-time job and didn't really need their extra part-time gig, which gave them the upper hand. OP's part-time boss knew this, and yet still threatened to fire OP unless they started working for them full-time. OP happily left, of course, and their already understaffed boss totally shot himself in the foot. Pro tip: if you're desperately understaffed, firing one of your only remaining employees is probably not the move.
“I had that with a second job once. Owner said it was my main priority. No, the job that pays me a salary, benefits, and time off is my priority. This is just extra income” said u/CPolland12.
“In the UK most retailers will only give people part-time hours some only zero hour contracts. And they can be real arse holes if you can't stop late because you have to get to your 2nd job. Because why can't you live off 16 Hours a week for minimum wage.” said u/Western-Mall5505.
“It's really just a simple case of the manager thinking that he has leverage when he doesn't. In the moment he thought that he could bully. I'm guessing that the text messages are him trying to correct things after he realized that his bluff was being called.” said u/pantsoptionalalways.
“Straight up. When I was 19 or 20 I was working two jobs, both retail cause I was a masochist. I had one of the co-managers come to me and tell me to go clean up a bunch of literal sh-t in the bathroom. I took one look in the door, saw how nasty it was, and just said no. 'You're telling me no? I could write you up for insubordination!' 'Go ahead and fire me, I'll quit before I clean that sh-t up. My other job would love to become my main one.' She glared at me, I stood my ground, and after about 30 seconds of silence she got on her radio and called someone else. I've been chasing that high for over a decade now. Nothing feels quite as good as getting to tell a sh-tty manager no.” said u/sykotic1189.
