Hi, I sent my flexible working request almost 12 weeks ago. I had a brief meeting which they said they would get back to me asap. It's 12 weeks on Monday which I know is the deadline for them to get back to me. I have a strong feeling that they have possibly forgot about me and won't get an answer Monday. As this is a legal requirement, what happens if they don't get back to me? Do I have grounds to make a complaint? Or to take it further?
