Codetermination appears to have had null, or slightly positive, impact on job satisfaction.

"The available evidence indicates that the European model of codetermination is neither a panacea for all of the problems faced by 21st-century workers, nor a destructive institution that is dramatically inferior to shareholder primacy. Rather, as currently implemented, it is a moderate institution with, on net, nonexistent or small positive effects. Board-level and shop-floor worker representation cause at most small increases in wages, possibly lead to slight increases in job security and satisfaction, and have largely zero or small positive effects on firm performance."
