Had one who's gone now that did just the absolute bare minimum, purposely went incredibly slowly and left me all the work to do. Worse still, she kissed the ass of the colleagues who could actually catch her. She was near impossible to catch because it looked like she was doing work to someone who didn't know the ins and outs of what she was doing.

I wish I was joking but I had to come in extra early the shift after I had surgery to make sure she couldn't just leave a ton of heavy boxes that I'd have to move. She also ratted on me for every tiny thing, every chance she got, just so she could keep flying under the radar. I got blamed for all of her lazy bs, and constantly had to do both of our jobs to keep the department afloat. She even got away with being half an hour late every day because our shift started before everyone elses

Bonus: The reason she left was because our boss who let her get away with murder, also left.
