“…Mainly American studies have observed negative effects on unionisation where managers use HRM techniques as part of an overt union substitution strategy (Kochan, 1980) or to raise job satisfaction through improved working conditions (for example, Freeman and Rogers, 1999;Fiorito, 2001) or to promote employee engagement and involvement (Belfield and Heywood, 2004). Machin and Wood (2005) posit that the incidence of flexible pay, pay that is managerially determined without any collective dimension, employee involvement and individual and non-union voice mechanisms, such as team briefings, direct management and communications channels, individual disputes procedures and non-union committees plus the presence of an HR specialist may help explain low unionisation in British workplaces but find no correlation between voice and HRM adoption and observe that unionised workplaces differ little from non-unionised workplaces in terms of HRM.…”
