Trade jobs that you can get with no experience include apprenticeship positions and entry-level assistant jobs. Electricians, plumbers, masons, welders, machinists, and heavy equipment operators can find apprenticeships through professional organizations, vocational schools, unions, or private contractors. Your duties in these entry-level trade positions involve undergoing training on the job while assisting a skilled tradesperson. Depending on the industry in which you work, you may also undergo classroom training and safety training. The number of job responsibilities that you have gradually increases during your apprenticeship until you finish and earn professional credentials. These programs tend to last around three to four years.
