Some Toronto District School Board and Toronto Catholic School Board students may be without a ride to and from class after a possible strike between bus drivers and their union.

A letter was sent home to parents on Monday warning them of the potential strike as negotiations continue between the First Student Inc. and Unifor.

“The union continues to meet with the company, and remains optimistic that an agreement can be reached without a labour disruption,” Unifor said in a written statement. “While 72 hours’ notice of a strike or lockout is required, Unifor Local 4268 has instead given the company 10 days’ notice.”

The school boards are not involved in the talks, but shared the same frustrations as some parents.

“We want to give parents as much as time as possible to make accommodations,” TCDSB spokesperson John Yan told CTV Toronto said of the possible job action.

“We know childcare is hard to find. This will be a significant disruption if (the) strike does happen,”

At the beginning of the school year, parents faced a similar problem as a bus driver shortage affected hundreds of students. Parents were forced to change work schedules to get their children to and from classes.

Unifor said in their written statement that they had “served notice to First Student that the deadline for the employer and the union to either reach a tentative agreement or be in a legal lockout or strike position” is at midnight on Nov. 3.
