I've never been fired, thank the stars. But I remember one time a woman at my store claimed she'd been fired for being pregnant.
What happened was she'd gone into the store one day for a meeting with a supervisor, and came storming out making her claim. The thing was, she had been messing up other people's schedules because of things that happened outside of the store.
For one example, I was about to take my break when she asked if I could wait because she needed to go do something. I later heard she'd done similar things like that to others.
Of course, people don't want to admit they're wrong, so they'd rather play the victim.
