Hot desking is often found in workplaces with flexible schedules for employees, where not all employees are actually working in an office at the same time or on the same schedules. Employees in such workplaces use existing offices only occasionally or for short periods of time, which leaves offices vacant. By sharing such offices, employees make more efficient use of company space and resources. However, hot desking does come with disadvantages—these include a lack of permanent space, an unclear work hierarchy, and possibly inconvenient communication between members of a team.
