Employers do have the right to yell at employees. Swearing might not be nice but it's not illegal. Unless the employer discriminates on the basis of race, gender or age, they can reprimand an employee.
Generally yes, unless the swearing contains derogatory remarks based on your age, race, religion, disability, gender or any other categories that are protected by federal law. You can also check with the GA state agency that administers the employment discrimination laws if you believe that the swearing is related to your particular status that may be protected by state law. The courts have stated that the employment discrimination laws are not intended to be a "clean language law." If you work in a hospital, there may be special rules that could apply.
