Supervisor The Occupational Health and Safety Act (OHSA) defines a supervisor as a person who has charge of a workplace or authority over a worker. This is a broad definition that can apply to many different people in a workplace, including people in management, on the shop floor, in a bargaining unit, and individuals whose job title does not include the word "supervisor". The definition of supervisor has two separate parts. Having either charge of a workplace, or authority over a worker, is sufficient for a person to be a supervisor. In general, "charge of a workplace" refers to broad control over the planning of work and how it is carried out, while "authority over a worker" can be seen as a more specific power to ensure a worker's compliance with directions.
