Canadian generation Z employees experienced a decrease in happiness of 0.4 points in April, according to a new survey by ADP Canada.

The survey, which polled more than 1,200 employees, found that, on a scale of one to 10, baby boomers reported the highest happiness score (7.3), followed by millennials (6.6), generation X (6.5) and gen Z (6.4).

The national work happiness score was 6.6, representing a decrease of 0.1 points from March. More than two-fifths (43 per cent) of working Canadians reported feeling happy with their current role and responsibilities.

The survey also found work-life balance and flexibility (6.9) are the top indicators driving workplace happiness, followed by overall satisfaction (6.8), recognition and support (6.5) and compensation and benefits (6.2). Opportunity for career advancement was the lowest indicator for workplace happiness (5.9).

“When we look at the different generations at work, gen Z has the lowest work happiness score in April, which appears to be primarily driven down by career advancement opportunities, as only a quarter are reporting feeling satisfied with the options provided,” said Holger Kormann, president of ADP Canada, in a press release.

“Employers should consider placing more focus on career development and advancement within their organization by building opportunities for upskilling and reskilling and providing clear, measurable guidelines for career progression.”
