Good company, bad compensation - Project Manager PCL Construction Employee Review

My pay was way below market value, I went somewhere else and am making 35% more than I was there. I put up with it because I was sold that there was so much opportunity, but it never came to fruition for me. When I decided I was going to leave they tried to talk about what they could do for me at that point to keep me, but I had already committed elsewhere, and I didn't feel that was the time to try to make employees happy. We also were always short staffed, and managing much more than we should have with the staff.
