245. In the absence of a collective agreement contemplated in the second paragraph of section 244, the modalities of application of a worker’s right to return to work are determined by the health and safety committee established under the Act respecting occupational health and safety (chapter S-2.1) for the entire establishment where the employment that the worker is entitled to be reinstated in or to hold is available. In case of disagreement on the committee or if a worker or employer is dissatisfied with the recommendations of the committee, the worker or employer may request the Commission to intervene.
