People who operate Winnipeg's transit system for the disabled and others who need help say they are over-worked, underpaid and face harassment on the job.
Transit Plus drivers have sent a petition to the mayor and city council asking for a review of their working conditions.
The petition says most drivers work beyond standard hours and are paid less than minimum wage.
There are also complaints about a lack of oversight when it comes to the private companies awarded Transit Plus contracts.
Negotiations are underway.
