Although green training has been shown in past research to promote environmentally responsible behaviors at work, scholars have paid less attention to its influence on employees' eco-friendly behaviors outside of work. This omission is critical because confining green training research to the work domain obscures its benefits in promoting employees' pro-environmental behaviors beyond the workplace, and thus its role in supporting organizational efforts to conserve the natural environment. To address this gap, we examine the direct and indirect (via connectedness to nature) relationships between green training and employees' eco-friendly behaviors outside of work, including consumption of eco-friendly products, reuse of items and materials, and reduced consumption of resources such as water, electricity, and paper. We also examine the moderating influence of intrinsic spirituality on the direct link between green training and connectedness to nature, as well as the indirect link between green training and eco-friendly behaviors beyond the workplace. Using time-lagged, multisource data, we find support for our hypotheses. Our findings advance knowledge on the important yet largely overlooked role of green training in shaping employees' environmentally responsible behaviors outside of the workplace.

Research has shown that organizations with strong green policies can elicit positive employee attitudes, attract new customers, and benefit from increased sales (Kalyar et al., 2021;Yang et al., 2011). Employees are crucial stakeholders in the implementation of green policies, implying that organizations must invest adequate resources to not only encourage green behaviors but also ultimately align employees' interests with the organization's ecofriendly objectives (Ahmad et al., 2022;Ones & Dilchert, 2012;Paillé et al., 2014). In this context, the development and deployment of green human resource management (GHRM) practices, such as
