I was hired for 35hrs/week, $13 per hour for 2 kids ($455 weekly). It was less than what I felt I deserved, but I desperately needed a job and the hours and travel distance were good so I accepted. Luckily, the parents immediately needed more coverage than they first expected and I found myself consistently working at least 40 hours, and bringing home $520 or more. After a few months MB asked if I wanted to change from hourly to salary, a flat rate of $500 per week. She tried to explain that this is what they did with the previous nanny and that she loved it. She claimed that she often let her leave early and that she always worked less than 35hrs but was still guaranteed $500, and then pressured me to accept. I refused because it seemed like this would only benefit her, because even when paying hourly I was never let out early, and if being paid salary she would have even less motivation to let me go early or work less than my promised 35hrs.
I continued to work 40+ hours weekly, and was paid hourly, for my first year with them and I felt great about my decision. But now for the past year they have been sticking to my initial promised 35hrs, and I have gone back to $455 per week and not a penny more, if they can help it. Of course now I wish I had accepted the flat rate of $500 because I am missing out on a possible $45 more per week. But part of me also thinks that if I was getting paid salary that I would be doing well over my 35hrs every week.
Oh, and they have complimented me several times on how much better I am than their previous nanny who they had to let go because she was lazy and call out too much. So it really pisses me off that the "lazy" nanny was being paid better than I am when I'm working my butt off!
