Researchers analyzed 127 public school teachers' strikes in New Jersey during the 36 school years from 1945 through 1981, presenting their data in over 60 tables. Data were collected from newspapers, magazines, and journals; through personal interviews; and via a questionnaire survey of affiliates of the New Jersey Education Association and the New Jersey State Federation of Teachers. Variables covered included strike frequency, causes (whether salaries and benefits, working conditions, or negotiation procedures), geographic location, time of occurrence (year, month, and weekday), staff days lost, number of teachers on strike, teacher organizational affiliation, school district enrollment size, and school board appointive or elective status. A historical analysis of New Jersey's development of collective bargaining policies for teachers reviews the origins of teacher bargaining, depicts the teacher and board organizations involved, and describes the evolution of public policy. Statistical analysis using percentages and correlations examines the data for 1945 through 1977; an appendix analyzes similar data through 1981 and adds information on strike causes from 1968 to 1981. Among the researchers' conclusions are that New Jersey teacher strikes are infrequent and short and tend to occur in larger northern counties with elected school boards. (RW)
