I find it weird that every part time jobs tries to play off flexible scheduling as a perk. Their schedule isn't flexible, they decide what shifts they want me to work. It might be better than factory work where you always work exactly the same shift or you must take vacation (or sick leave but they demand a doctor's note) - but you can plan around that well in advance. Meanwhile every full time job I've had wasn't factory work and so the expectation was "work any 8 hours per day, make sure you show up for the important meetings)
