MONTREAL—After being locked out for five days, the 900 longshoremen in the Port of Montreal forced employers to rescind their decision to deny the 169 youngest workers a guarantee of 40 hours per week. The workers, members of the Canadian Union of Public Employees, won the guarantee decades ago. Union members agreed in exchange to end their boycott of overtime. Negotiations for renewal of the collective agreement, which expired in December 2008, will resume shortly.
