The duty to accommodate applies to all grounds of discrimination covered under human rights legislation and the Canadian Charter of Rights and Freedoms. When any barriers associated with those covered under legislation exist in a workplace, there is a legal requirement of the employer (or union if one exists) to oblige to the needs of the worker, allowing them to work in a manner that results in undue hardship. It is important that the accommodation allows the worker to be treated equally and with dignity. The responsibilities of the duty to accommodate are shared by the employer, accommodation-seeker, and union (if one exists).
