While these terms are related, they refer to slightly different aspects of employee scheduling. A “schedule” typically refers to the overall plan of when employees are expected to work, including specific shifts and hours. A “roster” is a list of employees and their assigned shifts, essentially a part of the schedule. “Shift” refers to a specific block of time during which an employee is scheduled to work. So, while they are closely related, they have distinct meanings within the context of employee scheduling.
