My work have declined my flexible working request with the reason that customers like the continuity of the same person. Not one of the eight prescribed business reasons, I've written a letter to appeal stating its not a businesslike reason and therefore I'd like to appeal, to which thatch have replied saying that they want me back full time in x role. I have written back again asking for an appeal again, they have sent back the same response. My first letter would have arrived 14 days ago now.
Acas have advised writing a third and final letter asking for them to reply within 7 days about the appeal and then if they still refuse they will take it further. Has anyone else experienced this? Tbh this is the last in a long line of issues with them, when I was pregnant they were constantly calling me in for meetings regarding performance even though I was more than meeting their targets that they had set for me is one excuse. What should I do next?
