You can't help them; they don't want it.
I temped for the first month or so of my current job, which meant I didn't have PTO back then. We had a snowstorm and the office was closed, so nobody could come in.
The full-time receptionist complained over and over about how they "forced her to take vacation time" and martyred it up about how her job couldn't be done from her home so she had no choice and poor her.
She kept going on and on until I finally piped up and said, "Well, at least you got paid. I had no choice about it either and I don't get vacation time."
She found something else to complain about after that. Some people just aren't happy unless they are miserable.
