Workers are quitting their jobs in record numbers, with the figure approaching 3.9 million in July – a hair shy of the record set in April in what has come to be known as "The Great Resignation."

But a new global study of 5,500 workers and small-business leaders finds the mass exodus is being driven mainly by members of Generation Z, those who has spent the last time in the workforce, and millennials?

The a study by software and data analytics company Adobe found that more than half of Gen Z respondents reported planning to seek a new job within the next year.

The generation also reported being least satisfied with their jobs, 59%, and with their work-life balance, at 56%. Nearly two-thirds of them, 62%, said they felt the most pressure to work during "office hours," even though they said they do their best work outside of normal office hours.

Companies are facing extreme difficulty finding workers, with more than 9 million open positions nationwide. A variety of reasons have been offered for this situation, including worries about the coronavirus, responsibilities caring for children or elderly relatives, and low wages.

The study suggests the trend will continue, with 35% of workers surveyed saying they plan to switch jobs in the next year. Of that group, 61% said they would do so to exercise more control over their schedules.

Another study released this week from human resources consultants Galagher found that 72% of companies surveyed either raised or plan to raise their base salaries in 2021.

But, numerous surveys taken during the coronavirus, have found that money alone will not be enough to satisfy workers, with schedule flexibility and additional benefits top of the demands employees are making of employers.

The studies come as businesses are grappling with a spike in coronavirus cases, spurred by the rise of the delta variant. This has prompted many companies to postpone office reopenings and require masks and vaccinations of their employees.

For many millennials and those in Gen Z, some of their earliest, formulating career years have been spent working remotely, leaving them to foster work relationships and rapport with their colleagues without the traditional structures of the office.

At the same time, the nation is engaged in a cantankerous debate over whether to mask up again in the face of the delta variant and whether to adhere to requests to get vaccinated.

A new poll released Thursday from the Associated Press-NORC Center for Public Affairs Research found that 47% of in-person workers are in favor of vaccine mandates, while 26% are opposed. Among remote workers, the numbers are higher, with 59% in support of vaccine mandates for people working in person at their workplace.

When it comes to masking mandates, 50% of Americans working in person favored them, with 29% opposed, the poll found.
