Does anyone know what the legal rules are around this. Apparently my employer has to continue paying my pension contributions while I receive SMP. The HR woman I met with was very very negative about flexing the amount up just prior to mat leave, and said the company wouldn't "expect" this. Is there anything to legally stop me flexing salary just before mat leave so that they have to pay as much as possible eg 70% (ie abusing the loophole)? Or could they stop this?
