A group of hippie socialists who want nothing but to fuck over the entire school system at YorkU.

Not that it matters, y'know, unless they get their 30% pay increase.
student: Fuck yea! There's gonna be a strike!
student 2: You know that it's gonna push our school into summer right?
student: ....fuck CUPE 3903. They're such fags.

Pretentious bastards who screw students out of their time and money buy kicking them out of school. They like to extort the not-for-profit york university for millions of dollars during times of economic crisis causing the whole system to shut down.
Father: "Son, how come you have to stay in school for an extra semester before graduating, causing you to miss out on half a years salary of your life?!?"

Son: "CUPE 3903 screwed me out of school so i couldnt take second semester because i had to work to pay tuition"

Father: "Those bastards"

A student union of promiscuous socialists who think they own and control York and women. Comprised predominantly of sexist powertripping manwhores, they coerce and manipulate female unionists into having secret 'relationships' and unprotetected sex with them perpetuating the increasing coincidences of the herpes virus. Everyone has pretty much slept with everyone else. Many of them are playing numerous women at the same time. They destroy their victims lives mentally and emotionally.
Women 1: Hey. Did you hear that Brad coerced and manipulated Jessica into having a secret relationship and sex with him by giving her drugs?

Women 2: No I didn't. When did this happen? Isn't that date rape?

Women 1: About a year ago. It is indeed date rape. He was seeing other women as well and having unprotected sex. He dumped poor Jessica into the trash when he had his fill. She is mentally and emotionally damaged now.

Women 2: wow. Poor thing. She never said anything about it. I hope she survives this. Brad is a fucking manwhore. Those socialist men think they can get away with anything. Talk about having a power trip and screwing over someone. Talk about his morals being different than his politics. Scum dogs cupe 3903 men are.
