Some of the highest-paying commercial jobs include construction managers, elevator mechanics, and dental hygienists. Elevator and escalator installers and repairers repair, maintain, and install escalators and elevators. Job duties include reading drawings, replacing faulty parts, testing equipment, and performing safety inspections. These professionals usually specialize in repair, installation, or maintenance work.
They need mechanical and problem solving skills, physical strength and endurance, and the ability to work at heights. These careers usually start with a four-year internship in a union, employer or industry group. Trainees learn about reading plans, electrical theory, parts of elevators and escalators, and safety. Most states require that installers and repairers of elevators and escalators be licensed.
They also need ongoing training to keep abreast of technological changes in the industry. Radiation therapists provide radiation therapy to patients with cancer and other diseases. They explain treatment plans, use machines to treat patients, keep treatment records, and monitor patients for adverse reactions. Radiotherapists work in hospitals, doctors' offices, and outpatient care facilities.
They need technical and interpersonal skills, physical endurance and a lot of attention to detail. Radiation therapists, who are among the highest-paying professional jobs, need a license in most states. To become licensed, they must graduate from an accredited radiation therapy program and pass a national certification exam. Radiotherapists can move forward by obtaining certification and additional education to become dosimetrists who calculate radiation doses for cancer patients.
Most of their work is done outdoors, where they install, maintain and repair solar panels on roofs.
