This is bad on the business, you can't stay in the business if you are not making money. Look like a Pro, work like a Pro, act like a Pro and you will get paid like a Pro. I think every time I regretted every minute of it. When I figured how many hours it would take me to do the job then the number of hours times my hourly rate. I don't think so if they were you would be working for them.
Employees work better separated.
Go help the person that was slowing down. I always figure it by how long it would take me. I then multiplied the number of hours times my hour rate to figure what I needed to make a profit. I sometimes would tell the customer that we would work for so much per man per hour. If I had 4 or more men I normally wouldn't charge for my time unless I was doing work over half the time.
