As a locum tenens anesthesiologist, your job is to work as a temporary fill-in employee for a company that currently has a staffing shortage. Locum tenens jobs can last from several days to several months, and many people in this role work with an agency to schedule and maintain a steady amount of work. In this role, you may take on any assignment that a regular anesthesiologist would, including giving anesthesia and monitoring patients for the duration of surgery or any other procedure. Locum tenens anesthesiologists may be asked to work nights, weekends, or holidays as needed, so flexibility in your schedule is essential to this job.
