I started a new school in September but they agreed I would move up the pay scale as usual having met the targets in my previous school (I'm on main pay scale). However this hasn't ever appeared in writing..and still hasn't happened. I got paid again today on my old pay and with no back pay. Is there a deadline for which they must do this/have done this by? Surely they can't just withhold it for half the year then just increase the back pay. I am entitled to the money by now in my opinion and am depending on it.
