I have been out of work for 16 months now and would do anything to be in a work environment where I was treated like family. I would look for another part time job for now but I wouldn't leave a good solid job behind even if the hours were cut. Is there a chance the company might fold? If sothat would be the only reason I would quit the job you have. Jobs right now are hard to find and the competition is intense. If you feel insecure in your present job then go for the new one. You can get used to anything when you have to.
