Struggling with return to work

Hi everyone, I wonder if you can help me.

I returned to work 4 days a week in May this year and I am really struggling with work. I feel like I am not contributing what I used to be able to, and my enthusiasm for it has all but gone. I have come back to a hugely changed role and organisation due to a merger while I was on maternity leave. I am grateful I wasn't made redundant but I am really struggling to learn all of the new processes and systems (this was never a problem before, I am usually the first to pick things up).

I have a demanding job managing clients with complex needs and so far I cannot get my work done 4 days, then this leads to issues on my day off (that my colleagues have to sort) or dramas when I get back to the office. And I am really really trying to stick to my days and hours so I still have my family time and some rest.

Does anyone have any ideas to get my mojo back or tips for managing my time at work better? I'm normally very organised and methodical but I truely feel like everything has changed for me since having my wee girl almost a year ago. I really feel like my brain has changed.

Please let me know if you have experienced similar and what you did, thanks in advance.

I think you are probably right. I might need to give it another month or two and see if it settles. If it doesn't settle I will have to talk to my boss and see if I can shift a few clients to some one else. My work hasn't really had to deal with mums returning to work or staff working reduced hours, it typically has a slightly older workforce in my role anyway. So it's hard for them to adjust to as well. Thanks heaps, it's nice to have someone impartial review how I'm feeling.
