But it doesn't matter what you think my duties are. And it didn't matter what my manager thought my duties were. It mattered what I thought they were. And on that day, considering the circumstances (some shit job I'm working for barely more than minimum wage as I work my way through college) I chose to decide that sweeping the parking lot was not an acceptable duty. Maybe I would have chosen differently if I'd desperately needed that job to feed a family, but that just goes to show that our lines are somewhat situation dependent.
