Yes - certainly a tricky one! I was doing 4 different roles when I went on maternity leave and it was exhausting trying to train everyone up. I made sure I documented a lot of my processes and spent a lot of time with the girl that was taking over from me. I obviously "over-trained" her though because she was a casual hired for the 12m I was off, but when I came back, they gave her permanent status and moved me to another department!!! I was quite upset by it at first because I felt they mustn't have been happy with me, she must've done a better job etc. I had to remind myself that when I started, noone really trained me, but when she started, I trained her with everything I knew so I was at least owed some credit for that. It turned out the role I was moved to was more for convenience sake as it was a role they had left unfilled for 6 months and it just made it easier to send me there rather than distrupt everyone else to slot me back in where I left off, and there was no need for me to go back to my old position. This one is better for me anyway as there is a lot less overtime (I never needed nor wanted the overtime) so I can go home when I need to be there for my son. I also just found out recently that the jobs I was doing was split up to 4 people! So obviously I wasn't made redundant by the new girl and now that I'm back I have managed to learn new skills which will only make me more valuable to the company. My advice is to try and document and train as much as you can so you can switch off and enjoy motherhood for the short period that you can be 100% mum and not work. They will manage, then when you go back they will be al the better for you having left and there will be new skills for you to learn and develop.
