If your employer has light duty work available, they are required to provide you with that position. They do not have to create a light duty position for you under the Workers' Compensation Act. If your employer fired you in retaliation for asserting a right under the Workers Compensation Act, they may have been in violation of section 31-290a of the Connecticut General Statutes. If you and your employer meet certain criteria you may also fall within the protections of both the American with Disabilities Act and the Connecticut Disability Act which would require them to provide you with a reasonable accomodation. I suggest you retain an attorney that is versed in both workers' compensation and employment law.
