Massachusetts: How contractors can avoid being “bullied by homeowners”

Andrea Goldman writes:

I’ve seen a new trend in contractor disputes lately, and it isn’t pretty.  Some homeowners are making unreasonable demands on contractors, and bullying them into doing work without getting paid.  They unreasonably withhold payments, or impose penalties for delays that they cause.  They expect contractors to do all kinds of extra work without being paid or changing the completion date.
