I have no doubt that my manager wont have an issue with it, wether or not managment higher than him do if he has to inform them im not sure. Can i ask how long you did both for before you went full time with the business ?
I didn’t do much self employed work, whilst still in full time employment. It was more of a way of setting up my business, training, accountancy etc. But as they were all official, I had to get written permission to trade, and still be PAYE.
My business only lasted 5 years. I had semi retired, and thought returning to the industry and doing small domestic work, would be enough to top up my pension. I didn’t really have a business plan. I did some subbing work for one company, but it was carp work, and the domestic work I did, never paid enough to pay the bills. During the end, some months I did not earn enough to pay myself a salary.
If I was starting out, you need to have plenty of contacts for work, and some sort of business model. Domestic work is cut throat, clients expect you to work for next to nothing.
Think carefully, before you jump ship.
