tl;dr: A study of 7,704 healthcare employees found that fully remote workers reported the highest well-being, hybrid workers came second, and onsite workers scored lowest—with remote employees also using more positive language about teamwork and culture. Higher well-being correlated with lower turnover a year later, suggesting return-to-office mandates may hurt retention. Researchers attribute the gap to autonomy, flexibility, and the elimination of commute-related stressors.
