Office based role, currently working in office during covid.
I agreed a flexible working request with employer last year so right now i'm 9-5/8-4 depending on day.
There's been some flexibility and homeworking over covid but with child starting school in Sept and being back in office now I wanted to be able to pick up 1-2 days a week.
Requested to employer to work 7-3 or 8-3 (with extra hour another day) - basically I'm open to arrangement/agreement that means I can do 3 o clock pick up at least 1 day a week if it means compensating hours on another day.
My contracted week is 35 hrs a week but where i work there is a a line in contract that says I have to be in the office 35 hours a week + any 5 hours as and when business needs me to (e.g. there's a project to get over the line and they don't want to pay overtime). So essentially it's a 40 hr week contract (listed as 35 + 5 in contract) but we work 35 hour weeks unless business needs us to do the extra 5 hours. Everyone works to 35 hour weeks, unless they're trying to complete project.
When I put in flexible working request last yr they agreed it based on 35 hours. They never tell anyone to be/agree to be in the office more than 35 hours. Most people do usual 35 hours and don't do extra hours unless busy, so it's basically unmonitored.
They rejected the initial request because they said i need to agree a 40 hour working week with them this time not the 35 hours I had to agree on my last flexible working request. I'm looking at my hours and it means really long days 4 days a week (I've been told I have to take a break).
I completely understood request could be denied for business reasons and I know picking child up not a right but I've not had to do more than 35 hours a week so far (2.5 yrs in role) and i'm panicking at trying to get the extra 5 hrs pw in. Won't get additional compensation for hours and the people I sit next to will still be doing 35 hr weeks while I'm doing 40.
Is there a way I can argue this tactfully or do i just have to resign myself to the fact they're completely within their right to do this :(
