I'm currently on maternity leave with DS2, 7 months. We also have DS1, 2 1/2. Planning to go back to work just before Christmas when DS2 is nearly 9 months old. As I have nearly a month of accrued holiday, I've decided to work a 4 day week in Jan and Feb so that I can ease back in gradually. I did this with DS1 and it worked out well. However, I am pretty sure that I will only want to do 4 days per week permanently and so will plan to make a flexible working request which may/may not be approved. I was planning on making the request in February or March so, if approved, it's effective in April (we're planning a holiday in March so would be off two weeks anyway so no sense in it starting then). The reasons for not making the application then are i) I can use my holiday to work a 4 day week until then and ii) I want a period of time back in the office to see how a 4 day week pans out and whether it's workable long term and (iii) it if goes well I can say, look, I've been working a 4 day week for 2 months and it's workable. It all made sense to me but now I'm starting to worry about what if they refuse the request and whether I would like the certainty of knowing I can do 4 days permanently. I also have concerns that my maternity cover is trying to steal my job so a frank discussion with my boss in the forum of a flexible working application could help air those issues and put my mind at rest, or not as the case may be! What would you do??
