The results show that: (1) Decent work has a signiffcant positive impact on organizational citizenship behavior. (2) Demand satisfaction plays an intermediary role between decent work and organizational citizenship behavior. (3)Resilience will positively moderate the direct impact of decent work on demand satisfaction. Specifically, the higher the level of employee resilience, the stronger the positive impact of decent work on demand satisfaction.
