Because apparently it would be unfair on the other managers as they would have to cover me on the extra day I wasn't at work. (requested full-time over 4 days not 5). And they don't see it as a viable business option currently. I have emailed them back saying I am now going to have to consider my options etc.. . I got one back saying sorry your disappointed here's a link to appeals process. I'm gonna fill it out but not holding out much hope as my previous manager fraught it with a union and still got turned down. We are the only two managers to have children. I think it is descriminant but I have no idea what to do about it x

I've done it working as a teacher. There is a request for flexible working letter template by the union NEU or NUT online. You have to write a lot about why it would benefit the company moreso than your own benefits
