So we've hired this new employee and last month I gave her a ton of duties to do, but she focused on one I explicitly told her not to do as I had a handle on it. She had done it the month before so I suppose there's some familiarity to her but it distracted her from other duties.  


So I approached her about it and mentioned it, she said she wouldn't do it again.  


Well this month same thing, she's working on the thing I told her not to, and foregoing duties that actually need her attention.  


So, AITA for coming down on her for this?
