This study examined the impact of dissent and workplace freedom of speech on employees’ well-being (subjective, psychological and workplace well-being). Data for the study were collected through an online survey distributed to employees of various organizations. The findings revealed that upward dissent was positively related to subjective well-being (consisting of life satisfaction, positive affect and negative affect), psychological well-being, workplace well-being, and workplace freedom of speech. Lateral dissent was positively related to negative affect, workplace well-being and negatively related to life satisfaction and positive affect. However, there was no relationship between lateral dissent and psychological well-being. Workplace freedom of speech was positively related to psychological well-being and workplace well-being. Practical and theoretical implications are discussed.
