I'm looking for a bit of advice from anyone who thinks they can help! I've been working as a freelance illustrator for just over 2 years and met a local business man who writes childrens books. After illustrating the first book he kept phoning for other things to be done like posters and leaflets, but refused to pay for this work. He said the images were already drawn and so assumed he wouldn't have to pay again. He keeps trying to get me involved with the running of his business and inviting me to meetings that I don't feel I have any role in. I'm getting really stressed about this as I find myself having to make excuses not to go to these meetings and events. I want to be honest but he's the kind of person to really throw his toys out of the pram. How should I approach this?
