I have a main full time job and start maternity leave in 4 weeks time. I also have a casual job behind a bar doing occasional shifts. Basically they txt me at the beginning of every month with available shifts and I say if I want to do any of them or not. I presume once I go on maternity leave from my main job I won't be able to do any 2nd job shifts? Am I right in thinking it would affect my maternity pay (SMP)? I won't get maternity pay from the 2nd job obviously as it's casual but it's all above board paying tax and NI.
