This study broadens the application of the justice and OCB concepts beyond pay and job satisfaction to capture previously uninvestigated effects by examining the link between communication satisfaction (CS), perceived justice, and organizational citizenship behaviors (OCB) among Chinese employees. We predict perceived justice will mediate the relationship between CS and OCB. We also predict CS will mediate the relationship between perceived justice and OCB. Quantitative analyses were used to analyze the relationships. FsQCA was used as an additional technique to test the mediating effect. Results show that OCB were influenced by CS and perceived justice. CS is a mediator between perceived justice and OCB. Perceived justice is not a mediator between CS and OCB. The finding points to the need for enhancing communication practices and creating a fair working environment in order to encourage discretionary behaviors. Theoretical and practical implications are discussed along with the limitations. (C) 2016 Elsevier Inc. All rights reserved.
