Why your help is unhelpful: A multistage mediation model exploring mechanisms linking unhelpful workplace social support to work engagement.

Recent occupational health research has begun exploring unhelpful workplace social support (UWSS). UWSS refers to actions taken by a colleague that the recipient believes are intended to be helpful but are perceived as ineffective. For example, a colleague may provide help that is not wanted or do something incorrectly while providing aid. Despite the perceived good intentions of UWSS providers, empirical research suggests that UWSS is a potent workplace demand negatively associated with occupational well-being. The mechanisms that link UWSS and reduced occupational well-being, however, have yet to receive empirical examination. We integrate the job demands-resources model, conservation of resources theory, and basic needs theory to construct a multistage model linking UWSS to reduced work engagement via the frustration of basic psychological needs and the consequent experiencing of negative emotions. We test this model across two studies-a three-wave weekly study (N_{Level 1} = 960, N_{Level 2} = 320) and a 5-day daily diary study (N_{Level 1} = 1,680, N_{Level 2} = 336)-and find several significant direct and indirect effects. Across both studies (though at different levels of analysis), partial support was linked to reduced work engagement via the frustration of both the need for competence and relatedness and the experiencing of negative affect, while in Study 2, a daily link between undependable support and work engagement through relatedness frustration and the experiencing of negative affect was found. Implications for research and practice are discussed, and future research directions are offered. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
