Everybody wants hours but nobody wants to work. Costco has been the exception to this rule though. Truthfully, I would rather schedule 4 TM's for 20 hours instead of 2 TM's for 40 hours. Better reliability in my experience. It may suck for the TM but you control your journey. Nobody is making you work at Target. If you like the job and want 40 hours... I would suggest working up to TL status, get a pay bump, bennies, and 40 hours. If you aren't interested in pursing a TL position then x-train, swap shift board, open up your gahdamn availability(not directed at op but in general). If that doesn't work for you... then oh well.
