Part-time by choice
Over the past three decades part-time employment has grown steadily. With almost one in five workers putting in less than 30 hours per week at his or her main job, part-time labour has become a major form of non-standard work. As a consequence, ongoing issues surrounding part-time work, such as job quality, security, pay, and benefits, have become more important than ever.
Although the part-time employment rate decreased slightly in the late 1990s, the proportion of part-timers who willingly engaged in such work and did not want full-time work, increased. Consequently, the proportion of involuntary part-time workers—those who would prefer full-time work—has decreased (Akyeampong, forthcoming). This study looks at those who voluntarily work part time, as well as their reasons for doing so, their levels of work-related stress, and their job characteristics (see Data sources and definitions). Comparisons are made with full-time and involuntary part-time workers. The article begins with an overview of the growth in part-time work.
An upward trend
The percentage of workers employed part time grew from 12.6% (1.2 million) in 1976 to 18.5% (2.7 million) in 1999 (Chart A). This trend is not unique to Canada, as part-time work has increased in most industrialized countries (see International comparisons). One-third of the net increase in the part-time employment rate since the late 1980s can be attributed to employment increases in industries with already high rates of part-time work (see Decomposing changes in part-time employment). However, the more important factor has been an overall trend toward increased part-time work across all industries.
A number of well-known, sometimes interrelated, factors are thought to be behind the widespread increase in the use of part-time work. One is the development of a more globally competitive service-based economy. Since the evolving economy has brought technological change to the workplace, extended operating and production schedules, and increased fluctuations in business activities, firms have been inclined to use more part-time labour (Tilly, 1991). Employers have embraced a more contingent, flexible workforce for cost-saving reasons as well: "In a climate of increased competition, employers sought to reduce their labour costs and increase their workforce flexibility by decreasing their core full-time, permanent workers and hiring more workers on a part-time basis" (Schellenberg, 1997).
Some of the increase in part-time employment may also have come from the supply side, as more workers are looking for flexibility and ways to balance their home and work lives. Indeed, the percentage of part-timers who have adopted this work arrangement voluntarily has recently increased, reaching 73% in 1999, up from 69% in 1997. 1
Finally, demographic change can also contribute, as proportional increases or decreases in populations with high part-time rates, such as youths, can affect overall part-time rates. Analysis of this factor actually shows a dampening effect on the part-time work rate (see Decomposing changes in part-time employment), offsetting the effects of industrial employment shifts and the overall trend toward part-time work.
Youths and women predominate in voluntary part-time work
The number of voluntary part-time workers reached 2 million in 1999, representing 14% of all employment and 73% of all part-time employment (Table 1). These workers were most often aged 15 to 24 (40%) or women between 25 and 54 (40%). Respective figures for full-time workers were 10% and 33%. Youths and women aged 25 to 54 also made up the majority of involuntary part-time workers (73%). However, compared with their voluntary counterparts, involuntary part-time workers were more likely to be core-age adults (25 to 54)—65% versus 46%—attesting to their greater preference for full-time work.
The skewed demographic distribution of voluntary part-time workers is better understood when education and family characteristics are examined. For example, 81% of young voluntary part-time workers were attending school, compared with only 8% of youths working full time and 11% of youths working involuntarily at part-time jobs. This finding accords with the main reason given by both young men and women for working part time: roughly 90% of youths did so in order to attend school.
Consequently, since so many voluntary part-time workers are still young and attending school, their average level of education is lower than that of full-time or involuntary part-time workers. For example, 86% of voluntary part-time workers aged 15 to 24 in 1999 had a high school education or less, compared with only 65% of full-time workers. However, once people reach age 25 and have completed most of their schooling, full-time and voluntary part-time workers have strikingly similar levels of education—higher than that of most involuntary part-time workers (22% were university graduates, versus 16%).
Roughly 4 out of 10 men and women with full-time jobs, aged 25 to 54, had at least one child under 16 at home. This is in stark contrast to voluntary part-time workers, in whose case 61% of women and only 27% of men had dependent children at home. These differing rates are not surprising, given that 35% of women voluntarily working part time reported doing so in order to care for their children. Only 4% of men gave this reason. loyment between 1987 and 1999.
Reasons for choosing part-time over full-time
The Labour Force Survey asks all "voluntary part-time workers" the main reason for not wanting full-time work (see Data sources and definitions). The reasons given for choosing part-time work vary substantially by age. In 1999, most youths said school attendance was their main reason for working part time (92% of men and 86% of women), while older workers (aged 55 and over) stated personal preference (87% of men and 85% of women) (Chart B). Older workers choosing to work part time are most likely doing so to ease into retirement. On the other hand, 25-to-54 year-olds tended to report a variety of reasons, which differed by sex. Although personal preference for part-time work was the main reason for both men and women (44% and 45%, respectively), family responsibilities were almost as common a reason for women (44%) and going to school was a strong second for men (26%). Only 6% of women in this group were attending school.
Job security and earnings: voluntary part-timers in the middle
In terms of holding down more than one job, voluntary part-time workers in 1999 had a rate closer to that of full-time workers (8% versus 4%) than to that of involuntary part-time workers (14%) (Table 2). This is a reasonable finding given that the latter would prefer to have full-time work, and multiple jobholding brings them closer to that goal.
Self-employment was much more common among voluntary part-time workers (29% of those 25 and over) than among either full-time (18%) or involuntary part-time workers (20%). The desire to work part time may be one reason some people move into self-employment, as it allows greater flexibility and control over work hours.
Half of all part-time jobs, both voluntary and involuntary, were in sales and service, compared with only 19% of full-time jobs. (Sales and service positions are often scheduled outside 9-to-5 hours, thus creating a need for more short-hour work schedules.) On the other hand, 11% of full-time employment was found in management occupations, compared with just 3% of part-time work.
Rates of unionization and job permanence were higher for older than younger workers, as were those for full-time workers. For example, 36% of full-time workers aged 25 and over were in a unionized job, compared with 31% of voluntary and 34% of involuntary part-time workers. Proportions of workers with permanent jobs were more varied: 93% of full-time workers, 86% of voluntary and 74% of involuntary part-time workers. Similarly, average hourly earnings were highest for full-time workers aged 25 and over ($16.01), second highest for voluntary part-time workers ($14.48), and lowest for involuntary part-time workers ($11.99). Not only were job security and wage rates higher for voluntary (compared with involuntary) part-time workers, but work-related stress tended to be lower for this group (see Work stress).
The growth in part-time work has made it an important factor in the workplace. In 1999, almost one in five workers spent less than 30 hours per week at his or her main job. Furthermore, whether out of personal choice or to accommodate personal circumstances, such as the wish to attend school or to care for young children, 73% of part-time workers would rather have been engaged part time than full time. Although voluntary part-time workers fare better than their involuntary counterparts, their wages and job security are still below those of full-time workers.
