I recently left my job at Company A where I was working on separate contracts to Companies B and C. Now I'm an independent subcontractor to Company B. I left because I wanted to work less hours, work from home, and spend more time with family. When I told my old company I'm leaving, they said they would've let me work less and from home if I had asked (I assumed they'd say no given policies) and said to let them know if things don't work out.
Now I'm regretting it, I'm wasting so much time on setting this company up and I don't want to do the overhead that goes with it - invoices, contracts, finding new contracts, etc. I just wanted to make life simpler so I can spend more time with family. My first contract is for 5 months and then up for renewal. Can I return to my old job after that contract is over and say this just isn't for me? Is that too soon? Will I be seen as a flip flopper? What will that do to my reputation?
