Canadian border workers could begin job action next week. Here's what you need to know

Canada Border Services Agency (CBSA) workers are in a legal strike position and their union has set a new deadline of next Wednesday, while mediation continues, before any job action could start.

Here are answers to questions about how this could impact you at Canada-U.S. borders.

Who's involvedand what's at stake?

Over 9,000 workers with CBSA,out of about 11,000 total workers, could be part of anyjob action.

It would include employeesat airports and landand marine ports of entry.

They are represented by the Customs and Immigration Union (CIU), which is affiliated with the Public Service Alliance of Canada (PSAC).

The union originally set a deadline for any job action of 4 p.m. E.T. Friday, but the CIUhas now extended the deadline to Wednesday as mediation continues.

Being on strike wouldn'tnecessarily meanthey'd gooff the job.

About 90 per cent of workers represented by the unionare deemed essential, the CBSA said in a statement.That means they must continue to do their jobs, but would befree to participate injob action outside their working hours.

Possible job action could include"work to rule," when workerscould apply each and every one of their job's rules and regulations.

"You can create tremendous lineups of those trucks and tremendous lineups of people. It'll be very, very disruptive if they do work-to-rulebecause so many people cross that border every day," said Ian Lee, an associate professor in the Sprott School of Business at Ottawa's Carleton University.

For example, border officers could ask people, in each and every car,all ofthe questions permissible at a border crossing.

The Treasury Board of Canada Secretariat saidthat under the Federal Public SectorLabour Relations Act, employees deemed essential have to provide uninterrupted service and "cannot intentionally slow down border processing."

"CBSA management has already reminded our people and union leadership of this obligation," a CBSA spokesperson told CBC News. "We expect them to respect this, but are also actively monitoring operations to identify incidents of deliberate slowdowns.

"We are ready to take progressive disciplinary action in situations of illegal job action."

When could we see job action?

Workers have voted 96 per cent in favour ofstrike action if no deal is reached.

Both parties started a mediation process on June 3.

Has there been any progress?

The CIU said Thursday there wereno updates regarding talksbecause mediation is ongoing.

"We are still hopeful an agreement can be reached but the clock is ticking if the government wants to avoid any potential delays at Canada's borders," said CIU spokesperson Pierre St-Jacques.

In a statement, the Treasury Board of Canada Secretariat said it was "disappointed," by the threat ofjob action.

"Negotiation is a process of give and take," a spokesperson said. "The government is prepared to make concessions, but there needs to be movement on both sides. Canadians expect these outstanding issues to be resolved at the bargaining table swiftly, and the announced labour disruptions undermine the negotiation process."

What issuesare workersprepared to strike over?

Many of the issues on the table here are similar to those in other organizations: Worker protections, wages, and pensions and benefits.

But CIU president Mark Weber saidthey're also looking for provisions similar to those of other law enforcement agencies, like the "25 and out" retirement provision.

He saidthey're also looking for wage parity with RCMP officers, whohe said make about 15 per cent more than CBSA officers.

Can Ottawa force CBSA workers to keep working?

Well, technically.

The government can legislate workers back to their jobs,if they deem it necessary,but that action iscontroversial.

Two people who cross the border regularly for work told CBC News the slowdowns would be a headache,but neither supported back-to-work legislation at this point.

Brian Masse, NDP MP for Windsor West, told CBC News on Wednesday that his party wouldn't support back-to-work legislation.

What can I expectatCanada-U.S. borders?

In Windsor, Ont., representatives of twoborder crossings are urging both partiesto come to an agreement.

"As in all operations, adjustments must be made from time to time to improve the way stakeholders work together, including the negotiation of collective agreements," a statement from the Detroit International Bridge Company read.

"We will be working hard with the CBSA team to ensure there is minimal impact to the flow of trade and commuter traffic."

Neil Belitsky, CEO for the DetroitWindsor Tunnel, told CBC News that travellers could check their website and social media for updates to wait times.

"We understand that both sides are diligently working on coming to agreement," saidBelitsky.

Would a strike impact theeconomy?

Trade organizations and employers with workers who cross the border regularly have sounded off about the possible impacts of job action.

The Windsor-Essex Regional Chamber of Commerce saidit has penned letters to both the union's Weber and Anita Anand, president of the Treasury Board.

"Any strike by PSAC-CIU workers is going to have a major impact in our region, especially for local businesses," saidCEO Rakesh Naidu in a letter.

"Businesses that rely on a smooth and timely flow of cross-border goods and services could face significant challenges from this job action, including the automotive sector, which is heavily dependent on 'just-in-time' logistics."

That letter was co-signed by other local chambers, as well as the chambers of commerce in Sault Ste. Marie and the Niagara region, which are also border communities with a lot riding on a potential strike.

Another industry group, the Canadian Manufacturers and Exporters (CME), warned job action could impact the $3.1 billion in goods crossing the borders each day, including $400 million crossingthe Windsor-Detroit border.

"We are very concerned about the impacts that another critical supply chain disruption, this time at CBSA, will have on manufacturers," said CME president Dennis Darby.

"Extended delays will disrupt operations and production schedules, harming manufacturers, and their workers. Once again, manufacturers are being held hostage from circumstances outside their control."
