How to work as a customer service representative
Get your high school diploma.
Most jobs in customer service will require a minimum of a high school diploma or equivalent education. If you're a teenager or someone without their diploma, customer service is still viable for you in places like retail, but it may be harder to get a job.
Check with the employer or look at the application requirements before applying for the position. If you are older than high school age, look into ged programs provided by your local school or community college.
