Jobs are often classified into three markets or categories. Repetitive tasks on production lines are typical of unskilled labor. Upward mobility is possible but requires a company willing to train internally. Responsibility in unskilled jobs is usually restricted to meeting standards established by the company. Pay can be minimum wage or higher.
Many skilled jobs require a great deal of responsibility, technical ability and knowledge.
If you plan to enter the trades, study labor unions. In some states labor unions have gained a monopoly organizing the trade occupations. Knowledge of unions will also help you with the membership process when trying to get a job where unions are organized. While unions are experiencing an overall decline in the United States however, they usually still provide good pay and benefit packages. Entry-level management positions are training levels used to progressively advance college graduates or new hires into greater areas of responsibility.
