"Light duty" and "modified duty" are often used interchangeably in workers' comp cases. Technically, they are different. Light duty is less demanding work, physically and/or mentally. An example would be answering phones instead of stocking shelves. Modified duty means work in which obstacles that prevent injured workers from carrying out their essential job duties are changed, adapted, or eliminated. Therefore workers are performing the same job, just under different conditions - such as meeting with clients over Zoom rather than in person.
