Nearly half of U.S. employees quit abruptly without notice, study finds

Monster’s March 2025 analysis reveals that roughly one-half of U.S. workers quit their jobs without any notice during the previous year, a phenomenon the firm calls “revenge quitting.” The majority of these employees had held their roles for more than two years before exiting. Career experts attribute the trend to hostile workplace environments, ineffective leadership and a sense of being unappreciated, with compensation concerns mentioned by just 4% of respondents.

Nearly 60% of workers reported witnessing a colleague leave silently, leading to immediate project delays and morale drops. About 90% view such walk-outs as justified when conditions are poor, and half see them as a legitimate protest. Monster suggests that improving culture, recognizing contributions, providing clear career paths and training empathetic managers could curb the surge.
