This study investigated the phenomena of strike propensity and strike compliance among teachers in an illegal teachers' strike that occurred in British Columbia, Canada, in 1983. A questionnaire developed for this study was distributed in early 1984 to a random sample of 1,000 teachers from eight school districts; a total of 456 responded. The study sought information relating to teachers' strike propensity; their reasons for voting for or against the strike; their strike compliance (whether they participated in the strike action); their reasons for participating or not participating in the strike action; their attitudes toward the teachers' union; their feeling of identification with the teachers' union; their attitude toward the issue prompting the strike; their attitude on whether teachers should have the right to strike; and their level of concern over working conditions and the public image of the teaching profession. Appended are 24 references and 11 data tables. (SI)
