I work pt on Saturdays at a gallery/art coop. I enjoy it and need the extra income. I was encouraged to submit my art and see if they would show it. It was accepted and I am paying the same rate as the other coop members for the space. My manager now wants two of my Saturdays to be my 'volunteer' days rather than paying me 'because that's what the other coop members are required to do'. I cannot afford to take the loss of income. I'm now in a sticky situation and not sure how to salvage this. I'm going to have to pull my work out of the gallery. The manager is a grudge holder type so I'm also going to have to look for another job. And another place to show my work. I was just starting to feel like everything is going to be okay and now I'm worried about struggling again. Any advice?
