I returned to work in 2015 and was refused flexible working to go part time (3days). I had to step down my position from manager to supervisor. Now in 2018 someone who took my position has taken a new role along side the manager role, but he will only be a manager 3 days a week. I am currently in the process of raising a grievance against this being allowed, I have asked for an explanation as to how this is different from me asking to go part time. Anyone had anything similar or have any thoughts on this?
