The study, conducted online through the Pollfish survey platform from May 30 to June 4, found that 42 percent of U.S. workers currently hold more than one job, with the figure rising to 52 percent among Generation Z – those aged 18 to 28. The overwhelming driver, the survey shows, is financial necessity.

Amid inflation and the rising cost of living, 76 percent of all respondents said their current salaries have less purchasing power than those of previous generations. As a result, many are turning to "polywork," or multiple income streams, not as a lifestyle choice, but as a financial survival strategy.

The survey, which included responses from a total of 3,000 employed Americans with equal numbers of Baby Boomers (ages 61-78), Gen X (45-60), Millennials (29-44) and Gen Z (18-28), reveals widespread dissatisfaction with traditional employment models.

For instance, 62 percent said they would reject a high-paying job if it lacked benefits that supported their life outside of work, 67 percent still cited salary and financial benefits as the most important factors in evaluating a job, including 71 percent of Baby Boomers and 76 percent of all respondents said they have no interest in leadership roles, citing burnout, stress and office politics – with Gen X expressing this view most strongly at 80 percent.

Additionally, 61 percent of workers believe that the notion of a stable, full-time job is increasingly being viewed as a myth, with a striking 72 percent of Gen Z agreeing. At the same time, rising expenses are changing workers' expectations. Nearly 80 percent said inflation and higher prices have caused them to reassess what they consider fair compensation.

Mental health and flexibility are becoming non-negotiables for modern workforce
Aside from juggling multiple jobs, he survey also found that mental health and flexibility are becoming non-negotiables for today's workforce.

According to the report, 51 percent of all respondents and 63 percent of Gen Z said they would consider quitting their job if mental or physical wellness benefits were cut, even if their salary remained the same; 81 percent said they support flexible work hours to help parents and caregivers, this rose to 89 percent among Gen Z; 70 percent said they would trade most in-office perks for one paid mental health day per month; and 71 percent said perks not tied to essential needs, such as childcare or healthcare, are superficial and unappealing.
