It was no accident that the three major urban transit companies in Quebec, namely the Socit de transport de la Communaut urbaine de Montral, Socit de transport de Laval and Socit de transport de la rive sud de Montral, as well as most if not all their unions and employees are asking that we support a progressive and innovative policy.
Most employees are not currently happy within Quebec's top three transit companies.
My statement is definitely correct, because if most employees in Quebec's top three transit companies are seeking a policy change then that means they are not happy with the current policies. I think the system had difficulty with catching this because I worded it in a tricky yet simple way that did not match the original context.
