What is a shift swap?

A shift swap refers specifically to the exchange of working shifts between employees, where one employee takes over the scheduled shift of another employee. This practice allows for flexibility in scheduling and can help employees manage their work-life balance by accommodating personal commitments or unexpected situations.

In contrast, the other options describe different scheduling scenarios: cancellation of a scheduled shift refers to voiding a work period without replacement, while the assignment of extra shifts involves adding to an employee's workload rather than allowing them to trade shifts. Automatic assignment of shifts indicates a pre-determined schedule that does not involve employee choice or exchange. Thus, the defining characteristic of a shift swap is the mutual agreement between employees to exchange their scheduled shifts.
