The union representing locked-out bus drivers in Moncton is launching a public information campaign on Monday.

National leaders of the Amalgamated Transit Union will be in the city in hopes of pressuring city council to get back to the table.

The city locked out 90 Codiac Transpo bus drivers, service workers and mechanics on June 27.

An online petition aimed at ending the dispute has collected more than 350 names since Friday.

Sam Melanson launched the petition on Friday because she says the labour dispute is causing a lot of trouble for elderly people and those with disabilities.

Melanson warns that real problems will emerge if the dispute does not end before the school year begins in just a couple of weeks.

"The City wants one thing, the union wants another thing. They need to come and meet together in the middle because I don't think either side should be at a standstill," Melanson said.

"The whole point of doing this was for them to come for an agreement."

Tammy Haggerty, one of those who signed the petition, said she needs the bus to get to and from hospital for cancer treatments.

"Walking is impossible, so taking the bus is almost like a lifeline," she said. "Now that it's not there, I have to depend on family and friends. My family lives in Bouctouche, my friends work."

The petition urges the City and the union to come to an agreement to end the dispute.

The Local 1290 workers have been without a contract since 2010.

Wages remain a sticking point in the contract dispute. The City's last offer to the transit workers contained a 13.75 per cent wage increase over five years.

That deal would have been retroactive to July 2010, and it contained improved health and dental benefits. The City’s offer would have brought a bus driver’s annual salary to $51,000 in 2015.

By comparison, the union was asking for a 23 per cent wage increase over five years.

That would have brought a Codiac Transpo bus driver's annual salary to $55,120 in 2015, according to the City.

Paul Thomson, a spokesman for the City, said on Friday that it didn't look as if there would be a return to the negotiating table anytime soon.
