A skilled manpower is any worker who has special skill, training, knowledge, and (usually acquired) ability in their work. A skilled worker may have attended a college, university or technical school. Or, a skilled worker may have learned their skills on the job. Examples of skilled labor include engineers, scientists, software development, paramedics, police officers, soldiers, physicians, crane operators, truck drivers, machinist, drafters, plumbers, craftsmen, cooks and accountants. These workers can be either blue-collar or white-collar workers, with varied levels of training or education, even though they sometimes are called “purple collars"
In addition to the general use of the term, various agencies or governments, both federal and local, may require skilled workers to meet additional specifications. Such definitions can affect matters such as immigration, licensure and eligibility for travel or residency. For example, according to US Citizenship and Immigration Services, skilled worker positions are not seasonal or temporary and require at least two years of experience or training.
Skilled work varies in type (service versus labor), education requirements (apprenticeship versus graduate college) and availability (freelance versus on-call). Each differences are often reflected in titling, opportunity, responsibility and (most significantly) salary.
Both skilled and non-skilled workers are vital and indispensable for the smooth-running of a free-market and/or capitalist society. According to Alan Greenspan, former Chairman of the Federal Reserve Bank, “Enhancing elementary and secondary school sensitivity to market forces should help restore the balance between the demand for and the supply of skilled workers in the United States."
Generally, however, individual skilled workers are more valued to a given company than individual non-skilled workers, as skilled workers tend to be more difficult to replace. As a result, skilled workers tend to demand more in the way of financial compensation because of their efforts. According to Greenspan, corporate managers are willing to bid up pay packages to acquire skilled workers as they identify the lack of skilled labor as one of today's greatest problems.
