Wingbar. Don't despair. Early on in my career I was sacked by my boss (through no fault of my own) and so know how it feels. Bearing in mind that you were only being paid £12/ hour it's hopefully going to be the best thing that could have happened to you. You're now free to go and find a better paid job. I would suggest that you don't accept anything that doesn't have a retainer.
Unfortunately we're involved in a !!!!ty industry. I lost my first job because the bosses nephew had gotten his AFI rating the week before and had apparently been promised my job. It was bizarre. I actually briefed a student one Sunday afternoon, sent him out to pre-flight the aircraft, and then just before I walked out the door was pulled to one side and told that I didn't work there anymore...effective immediate. When I asked why I was told that there had been a complaint (??????) from a PPL holder who I had checked out a few weeks previously.
If you're free to move then there are jobs out there. Sunshine is good. Have you seen the recent adverts for a PPL school in Jerez, Spain. The chap that runs the place is one of the nicest guys around.
Good luck.
