I've personally been involved with more than one general contractor going under. When I was a young carpenter, I followed my best friend from job to job and contractor to contractor. When he walked off a job, the rest of us followed. He and I and a group of Dominicans (from Dominica not the DR) put more than one GC out of business because we'd walk and then we'd tell everyone we knew that they shouldn't work for said GC.
When I became older and my friend moved away, I took his place. It was so satisfying leaving a job and then receiving a phone call from the client a few days/week later asking me and the crew to come back and finish with promises that the GC would be out of the picture.
It's incredibly difficult to find skilled tradesman in the Caribbean that will show up sober each day and perform quality work. We always had the long end of the stick.
