Its ok, if you keep to yourself
I love the job, and proud of being a custodian. But the complete lack of communication, poor management and supervisors more concerned with being top dog than actually doing their job allowing the lazy to run rampant in most schools. Makes you wonder why you work hard, and do a good job... it certainly doesnt get you any further, all it does is get you sent out to more schools to do the work of the lazy.
Pay is not the greatest, but the sick days and other days do make like balance good. And there is the pension, which is a bonus if you get in young enough.
