Ahem, just because it’s hourly doesn’t make it not a “real” job --especially in this economy.
That said, I applied for at least a dozen or so crappy retail jobs in early Sept. Had interviews with four or five, accepted the only job actually offered to me. At which point I’d only attended a couple of interviews. Never mentioned my present crappy job at one of the later interviews, may have mentioned it in the last one (can’t recall). Would have happily accepted a job offer from the place I interviewed at only a week or two after accepting present job, but of course was not offered one (and quite frankly, I fear I shot myself in the foot by not implying hard enough that I was willing, nay, eager, to promise them to work there for the rest of my life).
At some level, crappy retail jobs and other hourly type gigs expect that if they offer 90 people jobs, 80 will accept, 70 will pass the drug test, 60 will pass the no-felonies background check, 50 will show up for orientation, and fewer than 40 will make it through the 90 day provisional period without No-call No-showing, being chronically late, or otherwise showing that they don’t really value their jobs.
So the employers treat the employees like disposable, interchangable cogs in wheels, and wonder why no one gives two weeks notice.
OK, my crappy retail job is with a Big Box Store–if you are applying to places with smaller workforces, some of my comments may not apply.
But in my opinion, it is perfectly legitimate to go to training for a day or two and decide that you hate it, and no longer wish to be employed by the company. You don’t have to tell Company A that in reality, your biggest reason for quitting is a job prospect with Company B. And certainly you can request that your training schedule be arranged around a " previous committment" without specifying “job interview with Company B”.
Saying you want to go to another job interview first is a bad, bad idea, unless YOU are special and being heavily recruited. Well, maybe not that bad an idea, but really, employers want people who will stick around through thick and thin. They know they can’t really get them or even just identify such people through a job interview, but they are going to try.
So take the first opportunity which presents itself, but it’s ok to keep looking for better opportunities–Employer A is looking out for its #1 interest and that’s not you.
