Volunteering is prevalent and on the rise in the United States, but little research has examined the connection between individuals' volunteering and their jobs. In the absence of that research, it remains unclear whether employees volunteer to build on meaningful work experiences or to compensate for the lack of them. Similarly, it remains unclear whether volunteering is beneficial to the job in some way or if it is a distraction, akin to "moonlighting." In this manuscript, several theoretical perspectives from the multiple domain literature - particularly, compensation, enhancement, and resource drain - are employed across two studies to examine the intersection between volunteering and work domains. Results suggested that volunteering was associated with both volunteer and job meaningfulness, and that the pull of meaningful volunteer work was even stronger when employees had less meaning in their jobs. The results further revealed benefits of volunteering for employers. Volunteering was related to job absorption but not job interference, and was therefore associated with better performance on the job. Implications of these findings for future theorizing on volunteering are discussed.
