A friend of mine with a fairly large operation ( 7 crews) sent out his 1400 contract renewals in January and 200 were signed in Jan , 200 in Feb and about 50 this month. Finally a bell goes off in his head and he starts calling customers. Well come to find out there is a new company in town. He hired all imported labor 2 years ago , these guys spent the winter going to all his customers and signing them up. Naturally they went after the best paying ones first. He now has 7 rigs and only enough work for 3 , and only enough guys to run 2 crews , the rest went with their amigos. He wants to sue the guys for stealing the customers. I told him not to waste his time , there is no law against starting a business and solicitating work from you ex employers customers. ( unless they were in his employ at the time they solicitated the customers) Remember that you could be training your future competition, they know your customers , and they do the work. A non compete clause is a great thing to have your employees sign.
