I have just started freelancing in the last few months. I have one ( my original) client who I work for around 8 hours a week, and have now been lucky enough to book other work around this. At the moment I am absolutely at capacity- it's good, but I am juggling. My client A has various people working flexibly for him- some employed and others like me are self employed. They specifically asked me to do my hours either on a Monday or a Friday because of the business needs. I fit my other work around this and have got into some kind of schedule with my projects . My client A has sent an email booking me onto an away day in a few weeks time on a Thursday. He didn't ask if I was available, just assumed I would be. On the day in question I do have a Webex meeting I am supposed to be running for another client- I have informed Client A and said I'm not available unfortunately. He seems very put out. I could possibly try and juggle things on this occasion but I feel like I am being treated like an employee- I do have other commitments after all. Should I just try and rearrange things on this occasion( my other client might not be happy then! ) or shall I use this as an opportunity to clarify our business relationship? Perhaps I am making too much of this- this is all new to me so thank you for assistance and patience!
