Pros
The modern world is hectic. An employer who offers a flexible schedule could gain a competitive edge over simply more salary. Allowing employees to work adjustable hours and to work from home a few days a week could create extremely loyal employees because they know they can juggle family demands and work demands with less stress.
Cons
Job sharing is a work arrangement allowing two employees to split the duties of one full-time position, making it an effective way for a business to accommodate unconventional employee schedules. For example, a working mother might need to spend more time at home than her full-time job allows. Creating a job-sharing opportunity might give her the flexibility she needs to continue with the company. If the company views her as too valuable to lose, it’s an attractive employee-retention strategy. But job sharing does have some disadvantages for the employer.
