He doesn't wear a silk hat and mingle with politicians, but the job superintendent, if he's smart, is every inch a diplomat. Sure, he's concerned primarily with construction details, work progress, equipment and materials. But he is also concerned with his people. The time he gives to morale problems or to meetings with business agents is not wasted when a smoother operation is the result. The good superintendent will be familiar with the agreements between contractors and unions in the area where the job is located. Then ,when he's ready to hire members of a particular union, he will already know the salary level and any benefits the workers are entitled to. This will avoid labor disputes later on in time. Once the job has begun, jurisdictional disputes can be avoided if the superintendent is familiar with the procedures outlined in a book issued from the Building and Construction Trades Department of the federal government. It is equally important to get along with the union representative and it is a good idea to talk to and get to know him before a dispute arises. The good superintendent will also get along with his workers realizing little things like convenient parking and toilet facilities pay off in higher worker morale and efficiency.
