Eighty per cent of workers in Sudbury are expected back on the job within four weeks and the remaining 20 per cent within in six weeks. Picket lines that went up July 13 last year at Vale's Ontario operations were dismantled after the deal was ratified by 75.5 per cent of members who voted in Sudbury and 74 per cent in Port Colborne. It was the longest strike in Sudbury's history and the longest strike in Vale's 68-year-history. There have been nine strikes at the former Inco operations in Sudbury since 1958, including an 8 -month one from Sept. 15, 1978 until June 7, 1979. It remains the biggest strike in Canadian history in terms of lost workdays.
