228. If it is established to the satisfaction of the labour commissioner seized with a case that the worker exercised his rights or functions under this act or the regulations, a presumption exists in favour of the worker, unless the employer shows that the worker abused his rights or functions, that he was laid off, dismissed, suspended, transferred or subjected to a discriminatory or disciplinary measure for exercising such rights or functions, and the burden of proof is on the employer that he had other fair and sufficient cause.
Sections 18 to 20, 118 to 137, 139, 140, 146.1 and 150 to 152 of the Labour Code apply, mutatismutandis, to this section.
