it really annoys me at work that i work so hard , and then slackers get paid the same amount kinda makes me feel invious, like they just get to walk around and get payed for it
I totally know the feeling! Have you tried bringing this up to your supervisor?
yes i have many times, but they do nothing about it sometimes it just makes want to quit so they are stuck with all the bad workers 
Ha, that would be some pretty good revenge. Maybe you should go ahead and find a new job where you will be appreciated.
