With all due respect to Julie Payette's past career and achievements, astronauts tend to be very ego-driven (to the point of being sociopaths in order to make it to that level, even just in their respective fields), prone to problematic lives post-space travel (see Lisa Nowak). Wouldn't surprise me if Payette's abusive behaviour is a result of her fall from grace.

She should step down and get help before it turns into something worse than workplace harassment.
