I work in finance and as such need to be at a meeting or two every day of the first week of the month. The remainder of my month end work is working through a tasklist and all tasks can be done anytime in the first week, in any order. The rest of the month I work on ad-hoc projects without real deadlines.
I currently work 37 hours, 7.5h M-Th and 7h F. WFH M,W,Th,F only in office every Tues.
I want to work 8h, M-Th and work the other 5 hours flexibly, staying WFH M,W,Th and going in for the day on Tues as i do now. I would vary the 5 extra hours to how I/the business suited, including a half-day on the Friday. I have a colleague in a very similar role who could answer questions if I wasn't around but I could still get my own work done before the deadlines. This would give me another half-day or day off a week outside month end which would benefit my mental health (i have chronic fatigue and several health conditions so I could organise my "life admin"/appointments on this day to leave my weekends free for recovery). But, at month end, it would mean I could still pop online for a few hours on a Friday to do my meetings and any other tasks I am needed for.
From that point of view, would you as a manager accept my request?
Separately, on a hypothetical note.
We do not have DC at the moment but we are planning to try for our first next year. We do not want to rely on grandparents for regular childcare but my mum works PT and could look after a DC for a few hours on a Friday once a month if we needed to (she has actively asked to do so FT but we said no). Once in a blue moon perhaps, I'd need to log on on a Friday while caring for the DC for an hour or two but this wouldn't be the regular arrangement and I'd ensure to work back a bit extra to compensate for any distractions. It would mean a lot saved in nursery/CM fees for that extra day and really utilising the full days we'd be paying for. Would this make me the WFH CF mumsnet loves to hate?
