Interesting topic, we had someone who didn't pass a question on their entrance survey for the job, but our pharmacy manager went through great lengths to get them hired regardless. Even went to the DM to get an over-ride for it. Once the tech was hired, she clearly wasn't equipped for the job (given about three weeks doing it, she didn't have a grasp on the system and wasn't picking up any of the info); she then started "calling in sick".
Three to four days of this, and we finally received notice that she put in her two weeks. She was still scheduled for days even though she had two weeks left, and didn't show. Needless to say, biggest WASTE OF TIME ever. Don't just hire anyone, this is coming from someone who has worked retail. I'm sure it's not uncommon though. The pharmacy manager just didn't have a good sense of judgment, especially with something as simple as an entrance survey.
