I've just started maternity leave at 37 weeks and intend to return to work at the end of February. I've just been informed by my boss that work won't be covering my teaching (I'm a university lecturer) but will instead be moving all my semester one teaching (ie. now until January) until I return to work (start of sem 2). This will mean that all the teaching I will have 'missed' while on leave will effectively be waiting for me on return (so will have to squeeze all sem one teaching alongside sem 2 teaching). I'm not sure of the legality of this when presumably work will be getting some sort of financial payments for my leave; certainly it doesn't seem right ethically. A colleague has suggested I get in touch with the union but wondered first if they are actually totally within their rights to do as they propose? I will be 'over hrs' (I'm 0.8 contract) but then so is everyone else...
