Anyway, I sub contract to a company doing council properties. Long story short neighbour of property I was working in asked if I could do a fuse board change as she was privately owned. I said yes and stated it would be through my company and not who I work for. She agree and the board was changed on a Saturday, anyway she now has called the company I work for and complained about me, my bids pulls me in the office and says that I should have asked for permission to do a job in my own time with my own bits and now he said he is going to invoice me for the time that one of colleagues took to test my work and check it wasnt his gear I used. What do you think about this, he has hinted that it will be several hundreds?!?
