I'm on maternity leave atm and my sort of ex manager (he is/was freelance, edging his way of of the company so not really my manager by time i went on mat leave but he still does work for them and we are in contact about projects when he needs help with one of mine) contacted me about doing some freelance stuff with both my work and new companies as clients. I'm not sure on the legality of working for him as a freelancer, working for my employer on a freelance basis.
I know I can work for other companies freelance but is him being the middle man enough?
Maybe I could do the work and not have any direct contact with my employer since he'd be my client and I'd keep everything separate with my own email address and laptop etc same as I would for any client or personal projects.
