Although there is developing evidence on the effectiveness of global HRM best practices in emerging and developing economies, little is known about the efficacy of those practices in the Middle East. This study examines the impact of High Performance Work Practices (HPWP) on both employee and organizational outcomes in Algerian firms. The results of a firm-level survey show that while HPWP are positively associated with employee work attitudes and motivations, this effect is not converted into organizational level outcomes. The results are discussed, and implications for future research are offered.
