First of all, I'd try charging a late fee....if you don't like working late, don't LET them make you.

And if you're sick, you're sick, right? Sucks, but I'm sure any logical person can get that. Even if you had a replacement, it's in their child's best interest to not be in that environment...

They sound disrepectful and maybe should be replaced. They're not living up to their end of things....

My mom often calls what I do babysitting. Sometimes I think it's the only word they know. I've never called my mom on it, since she used to "babysit"....
