Paccar locks out 800 employees in Ste-Thérèse

Paccar, a Ste-Thérèse truck manufacturing plant, has locked out its 800 employees amid stalled negotiations with the workers’ union.

On Saturday afternoon Paccar warned employees it would lock them out at midnight, citing a "no contract, no work" policy.

The workers’ collective agreement expired at 11:59 p.m. Saturday.

The company tabled its final offer late on Saturday, according to The Canadian Press. The union's negotiating committee called for an assembly on Sunday morning to deliberate on it.

Paccar did not move the lockout deadline to allow the union to consider the offer.

According to a news release issued by the union, Unifor-Québec, contract negotiations have been underway for the past two months.

In 2001, the then-union president locked himself in an office with 70 litres of water and went on a hunger strike to denounce what he called abusive workplace practices.

Paccar, a U.S.-based company, last locked out all of its Ste-Thérèse employees in 2004.
