Nearly 36 percent of professionals in the U.S. report feeling burned out at work and 33 percent say they are more burned out now than a year ago, according to new survey of 2,000 professionals from Robert Half.

The top factors contributing to burnout include heavy workloads and long hours (40 percent), lack of support or recognition from their manager (30 percent) and few professional growth opportunities (27 percent).

Those who report the highest burnout levels are Gen Z (39 percent) and Millennial (40 percent) professionals, working parents (38 percent), and professionals at small and midsize businesses (37 percent).

“With burnout on the rise, managers must take steps to monitor workloads, maintain open communication and support employee well-being,” said Dawn Fay, operational president at Robert Half.

Burnout is a top concern for organizations struggling to hire, the talent and business consulting firm said.

A separate Robert Half survey of more than 1,600 hiring managers found that their biggest obstacles in not being able to staff an open role quickly include employee burnout (42 percent), delayed project timelines (39 percent), decreased productivity of existing staff (37 percent) and higher employee turnover (36 percent).

“Burnout is not just an employee issue—it’s a critical business challenge,” Fay added. “During times of heavy workloads or delayed hiring cycles, employers need to address burnout head-on, or risk falling behind on critical projects and losing staff.”

Robert Half offers tips for managers to help counter burnout:

• Encourage taking time off: Support your team’s well-being by promoting regular time off and mental health days to recharge.
• Help prioritize projects and manage timelines: Assist your team in prioritizing tasks and managing timelines effectively to ensure manageable workloads.
• Hire additional support: Consider hiring contract professionals to ease workloads, allowing your team to focus on key responsibilities.
• Recognize and appreciate: Acknowledge and celebrate your team’s hard work and accomplishments to boost morale and reinforce a positive work environment.
• Foster open communication: Create a supportive environment where employees feel comfortable discussing their challenges and needs.
