If they pay well, and for the most part have been good to you, I would have a "sit down" with them... tell them that you have been there for them when they needed you and that you have no problem, (give them a "for instance" THIS job you're doing on Sat.) Tell them that YOU went to work for them on SATURDAY because they had "to have it now" and you came through for them. Then when they have a nice job, they contract someone else.??? Ask them WHY? And if it's, say, a 3000.00 dollar job and they got someone else because of a 100 or 200 bucks. I would tell them that "hasn't my devotion to your property and requests been good enough for a couple of hundred bucks?
