A retention specialist works for an organization to retain current customers and clients. Depending on the industry, your duties might extend to internal retention, which concerns employees. In either role, you must ensure that the customer or employee is satisfied with what they are receiving from the company. This career is partially a support position, and partially a complaints resolution position. You must have strong communication skills, as much of the job is spent talking to customers or employees face-to-face or over the phone. The qualifications required for this job vary depending on whether the focus is employees or customers, but a high school diploma or GED certificate and extensive customer service or human resources experience should be sufficient.
