The Public Service Alliance of Canada, PSAC, said it would expand its three-week long job action next week with strikes against the Canada Revenue Agency and other government departments, the Canadian Broadcasting Corp. reported.
Parks Canada's 4,800 employees have been involved in rotating strikes since Aug. 13, but the weekend walkout is the first involving the entire system of national parks and historic sites. Job actions at Parks Canada are likely to be less effective with the end of the busy summer season, the CBC said.
PSAC is pushing for larger raises for government workers.
Bob Allen, a union representative in Ottawa, told the CBC that thousands of government employees are nearing the point where they can legally strike.
"There's going to be a lot of people (off the job) in this town ... we'll probably have a problem figuring what we do with them all," he said.
