40 hours a week, 10 hours a day...then a new crew comes on for the next 40 hours. Then the first crew comes back...and so on. Large construction firms combine this with a second shift when they want to fast track a project.
The key is to sit down with your employess and work out the compensation issues and to make sure your state labor laws will allow such a program.
Good idea, I could to use both crews on any fast track jobs, and then have them on seperate jobs for the rest, 2 jobs at once. 40 won't do for us, we work 6 days a week or 48 to 50 hrs a week.
