Even before the COVID-19 pandemic, we lived in paradoxical times: while many individuals reported feeling more connected than ever, many also reported feeling lonelier than ever. Three in five adults reported feelings of loneliness. These feelings of loneliness, as well as stress, anxiety, and depression, negatively impact people’s desire and ability to engage at home and at work. An estimated 62% of the adult workforce consider themselves lonely, and the impact on business performance and the organization’s bottom line is significant. Lonely employees have higher rates of absenteeism, which costs employers more than $154 billion annually, and are twice as likely to quit, according to our recent study conducted for Cigna Corporation and Evernorth (Cigna’s health services business) and published in the Journal of Organizational Effectiveness: People and Performance. The study provides a deeper look at the costs of loneliness and opportunities for employers to support their workers, now and in the future. It is based on an Ipsos survey commissioned by Cigna of nearly 6,000 working adults across the United States conducted online from July to August 2019. With so much cultural and corporate attention being paid to mental health, now is the time for employers to re-examine their thinking and take bold actions to reverse troubling mental health trends. Today’s opportunity for leaders is to see workforce loneliness as an organizational challenge and shared responsibility rather than an individual’s issue to solve independently.
