PurposeDrawn upon the perspective of implicit voice theory, the purpose of this paper is to explore the underlying mechanism as well as the boundary effect in the relationship between paternalistic leadership and voice behavior.Design/methodology/approachMultiple-wave survey data from a sample of 368 employees in China were used to test the hypothesized moderated mediation model.FindingsThe findings show that both benevolent leadership and moral leadership related positively to voice behavior, whereas authoritative leadership played a negative role in influencing voice behavior. Employees' implicit voice belief played a partial mediating role between paternalistic leadership and voice behavior. Furthermore, perceived HRM strength weakens both the mediation relationship among benevolent leadership, implicit voice belief and voice behavior, and the mediation relationship among moral leadership, implicit voice belief and voice behavior. However, the moderated mediation effect of implicit voice belief on the relationship between authoritative leadership and voice behavior is not significant.Practical implicationsLeaders are encouraged to behave benevolently and morally whereas to avoid excessive authoritative style at work, so that employees can be encouraged to speak out. Organizations are advised to introduce management practices like training and development sessions and to improve employees' perceived HRM strength so that the implicit voice belief can be reduced, and the voice behavior can be stimulated.Originality/valueThe research provided a fresh theoretical perspective on the underlying mechanism between paternalistic leadership and employees' voice behavior by unveiling employee implicit voice belief's partial mediating role between paternalistic leadership and employee voice behavior. Furthermore, the study contributed to the literature of voice by adopting a more integrative perspective and exploring the role of the implementation of the organization's system, i.e., perceived HRM strength that provided a boundary condition in the above mediation model.

Background: Mental health disorders are major contributors to the global burden of disease and their inverse relationship with physical activity is widely accepted. However, research on the association between physical activity and positive mental health outcomes is limited. Happiness is an example of a positive construct of mental health that may be promoted by physical activity and could increase resilience to emotional perturbations. The aim of this study is to use a large multi-country dataset to assess the association of happiness with physical activity volume and its specificity to intensity and/or activity domain. Methods: We analysed Eurobarometer 2002 data from 15 countries (n = 11,637). This comprised one question assessing self-reported happiness on a six point scale (dichotomised: happy/unhappy) and physical activity data collected using the IPAQ-short (i.e. walking, moderate, vigorous) and four domain specific items (i.e. domestic, leisure, transport, vocation). Logistic regression was used to examine the association between happiness and physical activity volume adjusted for sex, age, country, general health, relationship status, employment and education. Analyses of intensity and domain specificity were assessed by logistic regression adjusted for the same covariates and physical activity volume. Results: When compared to inactive people, there was a positive dose-response association between physical activity volume and happiness (highly active: OR = 1.52 [1.28-1.80]; sufficiently active: OR = 1.29 [1.11-1.49]; insufficiently active: OR = 1.20 [1.03-1.39]). There were small positive associations with happiness for walking (OR = 1.02 [1.00-1.03]) and vigorous-intensity physical activity (OR = 1.03 [1.01-1.05). Moderate-intensity physical activity was not associated with happiness (OR = 1.01 [0.99-1.03]). The strongest domain specific associations with happiness were found for "a lot" of domestic (OR = 1.42 [1.20-1.68]) and "some" vocational (OR = 1.33 [1.08-1.64]) physical activity. Happiness was also associated with "a lot" of leisure physical activity (OR = 1.15 [1.02-1.30]), but there were no significant associations for the transport domain. Conclusions: Increasing physical activity volume was associated with higher levels of happiness. Although the influence of physical activity intensity appeared minimal, the association with happiness was domain specific and was strongest for "a lot" of domestic and/or "some" vocational physical activity. Future studies to establish causation are indicated and may prompt changes in how physical activity for improving mental health is promoted.
