“…Hence, the same HRM system can be interpreted in different or even contrary ways, and it is individuals' perceptions of this system that are most relevant to individual level attitudinal and behavioural outcomes (Guest, 1999, Gerhart, Wright, McMahan and Snell, 2000, Gratton and Truss, 2003, Gerhart, 2005, Conway and Monks, 2008, Kuvaas, 2008. Whilst a wide range of studies have examined how single HRM practices such as selection, training or performance management influence individual level behaviours (for an overview see Boswell, 2002, Boselie, Dietz andBoon, 2005), more recently researchers have argued that HRM practices and strategies need to be considered holistically rather than as individual practices to assess their impact on employee outcomes Mohamed, 2010, Snape andRedman, 2010). As individual practices can substitute, complement or conflict with other HRM practices (Wright and Boswell, 2002), scholars have increasingly focused on examining the effects of combinations of HRM practices, or so called HRM bundles on employee outcomes.…”
