Which of the following describes a compressed work schedule option?

A compressed work schedule allows employees to complete their full-time hours in fewer days than the standard workweek. In this case, working 4 days with 10-hour shifts exemplifies a compressed schedule, as it condenses the traditional 40-hour workweek into just four days. This arrangement not only provides employees with an extended time off but also retains full-time benefits and responsibilities within a shorter work period.

The other options, while related to work schedules, do not fit the definition of a compressed work schedule. A standard 5-day workweek remains the traditional format without any reduction in workdays. Flexible working hours refer to the ability for employees to choose when they start and end their day, but it doesn't necessarily reduce the number of days worked. Job sharing involves two or more employees sharing the responsibilities of a single full-time position, which also does not meet the criteria of a compressed work schedule.
