Researchers have assumed that employee support programs cultivate affective organizational commitment by enabling employees to receive support. Using multimethod data from a Fortune 500 retail company, we propose that these programs also strengthen commitment by enabling employees to give support. We find that giving strengthens affective organizational commitment through a "prosocial sensemaking" process in which employees interpret personal and company actions and identities as caring. We discuss theoretical implications for organizational programs, commitment, sensemaking and identity, and citizenship behaviors.Changing employment landscapes have weakened employees' physical, administrative, and temporal attachments to organizations (Cascio, 2003;Pfeffer & Baron, 1988). Employees are more mobile, more autonomous, and less dependent on their organizations for employment than ever before. To address these challenges, organizations are increasingly seeking to strengthen employees' psychological attachments by cultivating affective commitment-an attitude of emotional dedication-to organizations (Mathieu & Zajac, 1990;Meyer & Allen, 1991). Extensive research has demonstrated that affective commitment to organizations is linked to important behavioral outcomes ranging from decreased absenteeism and turnover to increased job performance (Cooper-Hakim & Viswesvaran, 2005;Riketta, 2002;Somers, 1995). Accordingly, scholars and practitioners continue to share a deep interest in understanding how affective commitment to organizations develops. This pursuit is a foundational task for organizational scholarship (Mowday & Sutton, 1993).Searching for new ways to strengthen employees' affective commitment, many organizations have adopted employee support programs (Hartwell, Steele, French, Potter, Rodman, & Zarkin, 1996). Employee support programs are formalized practices designed to improve employees' experiences at work by providing emotional, financial, and instrumental assistance beyond the scope of standard HR pay, benefit, recognition, and training and development programs. These increasingly common programs, ranging from employee assistance programs to work-family programs such as child care and elder care, provide employees with various forms of help and aid (Cascio, 2003;Edwards & Rothbard, 2000;Goodstein, 1995). Scholars typically assume that employee support programs cultivate commitment by enabling employees to receive support (Johnson, 1986;Perry-Smith & Blum, 2000;Trice & Beyer, 1984). When employees become aware of or utilize the services offered by support programs, they are more likely to feel that their work organizations value their well-being and thus reciprocate by developing affective commitment to these organizations. For example, the literature on perceived organizational support suggests that when employees feel supported by their organizations, they develop beliefs that their organizations care about their welfare, which further motivate them to strengthen their affective commitment to their organiza...
