I'll try to be as brief as possible. I am self employed but do a lot of work for one particular organisation. Love the work and prior to this also got on with everyone, it's pretty much my dream work and location etc is ideal.
A few months back someone was taken on in a management role, they are connected to the person I work very closely with and who all of my work arrangements are made through. Shortly after that a situation unfolded where both lied to me which caused my week to be far far harder than it needed to be, the lie was to facilitate them getting what they wanted. By saying making my week harder I'm not being wet, what I ended up doing was ridiculous. When tackled they both denied it despite me having proof. Since then it's been like an opening of the floodgates, whereas previously arrangements were made which were fair to us both I'm now absolutely at their mercy or I don't get the work. Just to add this work can involve long days and unsociable hours, I seem to now be doing the majority of those. My suspicion is that new manager is a bully, other behaviour has pointed towards that being the case.
I have taken it higher but support has been limited, we are having a meeting tomorrow to discuss everything but does anyone have any advice as to how I should go about things in that meeting? Honestly if the work didn't suit me so well in the past I'd just walk and I (and they) are aware I can do that. I just don't want to!
