The only maintenance guy, and when people don’t show up to run their line, I have to cover their machine.

Title says it, this place wants me to do everyone’s on the floors job, same pay. The place is old, dirty and nasty. Bathrooms never cleaned, break room never cleaned. Now I just accepted a new job offer, with a promising future and a raise. Should I give them my two weeks? Or just leave, they will be screwed as no one knows this building like the guy that retired and trained me for two weeks. Lol
