The effects of three types of work-life conflict in Canada were examined by using data from a set of work and family studies that were conducted in 1991 and 2001. The studies focused on the effects of the following types of conflict: (1) work overload; (2) work-to-family interference (where work gets in the way of family); and (3) family-to-work interference (where family gets in the way of work). The findings were deemed representative of the population of employees working for medium and large public and private organizations in Canada. The following are among the key findings emerging from an analysis of both datasets: (1) work-life conflict increased markedly during the 1990s; (2) parenthood remains more difficult for women than for men; (3) work-life conflict has a negative impact on organizational performance and on employees; (4) employees with high work-life conflict make more use of Canada's health care system; (5) role overload increases when role demands accumulate; and (6) work-to-family interference increases when role demands conflict. The study yielded 27 recommendations for employers, employees and their families, unions, and governments. A list of 37 publications documenting the 1991 study is appended.
