The mechanic’s job entails more than fixing a few cars. He must spend long hours in working conditions that are unusual to most other professions.
Mechanics work a 40-hour week and more, especially if the mechanic is the owner and sole proprietor. The owner operator must not only see to the day-to-day client needs but also to the business needs (bookkeeping, supply order and stocking, customer service). This can easily lead to a longer-than-normal work week.
Mechanics work on heavy machines -- the vehicles -- and some of the parts and tools used are under pressure. These pieces include torque wrenches and pneumatic tools. Mechanics are taught to strictly practice safety measures to avoid injuries. It is not uncommon to suffer minor cuts, burns and bruises.
Mechanics work in environments are often greasy and dirty because of the lubed car parts that they work with. The tools and large vehicles may make the environment loud as well. The need for ventilation in the shop -- to vent away fumes from the chemicals used in repairing and painting cars -- can make the environment drafty as well.
