It was a wrong number.
A women left a message for an employee, whom apparently had not shown up for work yet. All very normal.
Except, the women that hasn't shown up for work is on the schedule as a discharge cleaner.
Witney, I wouldn't have shown up for work either.
Susan, you need to talk to your boss about renaming this job title because, hopefully, it is not as bad as it sounds.
Side note: I assume this a hospital job but, come on, a discharge cleaner.
