In the U.S., workplace trauma, work-life balance and conflict/tension with managers were among the top concerns.

“Company leaders and people managers face an urgent question: Will they create a psychologically safe and engaged workforce, or will they perpetuate a culture of stress and instability,” said Alan King, Workplace Options’ president and CEO, in a statement. “Psychological safety—the belief that employees can express themselves without fear of negative consequences—is no longer just a workplace perk. It is a business necessity.”

Lack of psychological safety among employees can have big consequences for organizations. Failing to address stress and other concerns can lead to higher turnover rates, declining productivity and a disengaged workforce, according to Workplace Options.

“Our study is a wake-up call. If organizations do not prioritize psychological safety now, the next generation will enter a workforce defined by stress, conflict, and disengagement,” said Dr. Kennette Thigpen Harris, chief clinical officer at Workplace Options, in a statement. “Millennials have entered decision-making roles, the opportunity to build a workplace culture defined by trust, respect, collaboration, and wellbeing has never been more urgent.”
