And this is why you make jokes anonymously on FML and keep your fucking mouth shut at work.

Maybe she took it as a passive aggressive comment

eeess4 use a 4's fcdz it

Today, I tried to decipher what this comment meant. FML

having a stroke? better see a doctor

Just goes to show that in this day everyone takes everything the wrong way and has a negative attitude. Smh...terrible boss.

please use that spare time to find a new job

Maybe your boss took that joke as a sign that you didn't want to work extra anymore. Like: "you might as well make me fulltime now" to reinforce that you are actually parttime and should be treated as such

Seems more likely that the boss didn't want to risk OP pulling enough hours to count as full time because of some reason- usually it's because businesses don't have to give benefits to part timers, but if someone is working enough hours to qualify as full time, they become entitled to benefits.
