Final answer:
A telecommuting employee at a remote extension of the main office with clerical staff and a manager is working at a satellite office, which supports flexible work arrangements and aids in work-life balance.
Step-by-step explanation:
When a telecommuting employee works from a remote extension from the employer's office that includes a clerical staff and a full-time manager, the employee is said to be working at a satellite office. This type of office arrangement allows the employee to work remotely while still having access to some on-site resources and management, similar to what would be available at the main business location. These satellite offices can help reduce the conflict between work and family life by providing a dedicated workplace that is still conveniently located outside of the corporate headquarters, and they can support flexible work arrangements, fostering better work-life balance.
