First let me say that I actually like my job. The pay is decent but I don't have medical benefits (I'm in USA) and a long commute and I only work 25 hrs/week. I work in the education world, so money is obviously not plentiful for anyone.
I asked my boss if there was any possibility of making my job full-time. They said that I'd need to prove I “deserved” it. I didn't even know how to respond. How am I supposed to do a 40 hr job in 25 hrs without giving free labor? No doubt it would take a year or more to “prove” myself. And it's not even guaranteed that they'd increase my hours.
I like my boss and don't blame them because they're just answering to higher powers. But come on. People can't live like this. They wonder why there's such high turnover. Thank you for letting me vent.
