Occupations are categorized by skill level. A professional career, such as doctor or teacher, means the worker has undergone training and education. An unskilled job, such as cleaner or shop assistant, does not require such rigid training.
A white-collar job is a salaried profession, typically a desk job such as one in administration. More demanding, highly skilled white-collar jobs would include a doctor, an attorney or an executive. Blue-collar jobs are based on manual labor, or workers with technical skills. Higher-trained blue-collar occupations include fire fighters, police officers, foremen and truck drivers. Many websites offer personality and skill set assessments to help one determine a suitable occupation.
