Construction is a historic trade with several and ever-changing disciplines. Prior to 1980, the industry was focused on the worker in the field. Since that time, we have shifted more focus to project management, enhanced products and specialized consultants. When I was young, most of the experts were people who were journeymen that came from the field. Today, most managers and consultants have little to no field experience related to actual installation. I find many consultants look down upon the craft worker, while at the same time expounding on their experience in the field. Most had a summer job on the site and use that as field experience. This is not the same as being a journeyman.
Those who have prolonged time in the field know what it is really like. The work is typically physically taxing, requiring specific training and skills that develop over time (even the physical challenges are overcome as you train your body). It can be rewarding to work with people you have a common bond with. Construction banter goes with the career. To the bystander, it may seem like they dislike each other with all the insults and snarky remarks; though at times, they can speak an odd form of a compliment. Construction workers tend to make poignant jokes about other workers they like and respect. This makes no sense to people outside the trades. Some insults are ill-intentioned and some are a form of bonding. This juxtaposition is also what makes hazing so hard to identify and police. Consider many disciplines are tedious and monotonous. Banter can make the day pass and can be a form of team building.
