If I was injured at work do to a fall and my job sent me to a Dr. The Doctor ok me to return to work but with a restriction of lifting no more than 5

The employer is required to pay you for the time period that the doctor kept you off of work until he released you to go back to work. If the doctor puts you on a restriction, then they are not required to put you on any job that would exceed the restictions. However, if there is a job that they can provide you with that is within the restrictions, then under the ADA they have to make reasonable accomodations to put you in that job. If you have further questions, contact the Tennessee Department of Labor, Workers Compensation Division.
