(2013) collected data from 100 employees of selected manufacturing companies in Ibadan, Nigeria and concludedthat pay, performance bonuses, recognition and praise were significantly related to organizational performance, supporting Herzberg's motivation-hygiene theory.Apart from cash or monetary rewards, motivation theories and empirical studies also attest to the role of non-cash rewards in motivation especially in technology-based, high-paying jobs.
