Final answer:
The scheduling arrangement where employees work a set number of hours with varying start and end times is known as flextime. This allows workers to balance work and personal or family obligations more effectively. thus, the option d is the correct answer.
Step-by-step explanation:
In the scheduling arrangement where employees work a set number of hours per day at the workplace but are able to vary their starting and ending times, the term used to describe this is flextime. This system typically requires that employees work core hours but provides the flexibility to start and end their workday at varying times to accommodate personal or family needs. In contrast, telecommuting refers to the practice of working remotely, often from home, and potentially with more freedom to set work hours, and a compressed workday involves working longer hours on some days in exchange for shorter hours or a day off in the same workweek. Work sharing is a situation where two or more individuals share the responsibilities and hours of a single full-time job.
