I worked a lot of crappy jobs to fund my studies - working places that treated their employees like cheap fodder, only caring they showed up on time and moved A to B as fast as possible. You'd show up for summer shift one year to return the next to find your co-workers who'd been doing the exact same thing every day while you'd been gone with no suggestion of training or boosting their skills. McDonalds was the one place that I actually saw investing in their staff - training and promoting and pushing those they saw capable of going on the management track - even if they didn't have any qualifications that would put them on that path elsewhere. One guy I know from those days now has his own home and car and lives quite comfortably, having taken that training and transitioned into another business organisation. Certainly not something that would have happened if he'd taken the same minimum wage job down the road at the fancy restaurant.
