Before you flag it as a duplicate I think my situation is a bit different from others I've read on here. I am currently in school studying for comp sci and was supposed to get co-op job this summer so I canceled my planned trip to Europe. Now for reasons co-op never happened and I was stuck with nothing to do for the summer. I applied at places and got a job at a warehouse. The job is pretty dull and boring and I feel like I'm losing IQ working there. Now I got a job offer from a pretty big ISP to work in tech support but the catch is that I have to start immediately. I would really like to give a 2 weeks and quit properly but unfortunately that'd not an option. If I get the job at the ISP how should I go about quitting the warehouse on the spot?
