Needs theory, Alderfer’s ERG Theory, Herzberg’s two-factor theory or the motivation-hygiene theory, McClelland’s 3-needs Theory, Vroom’s expectancy theory, satisfaction-performance theory, goal-setting theory, Reinforcement theory etc. Whatever be the theory, the main point derived from them is that employees will be motivated if they get what they desire and value. A similar pattern was observed in Kalar’s (2008) study conducted in a radiologic science workplace. Kalar’s (2008) study presents a very interesting and different perspective on employee motivation in comparison with other researches on employee motivation.Radiological sciences workplaces comprise of healthcare professionals, technical personnel, caregivers etc., that deal with providing radiological services to patients. Hence, these workplaces employ highly diverse work professionals. Kalar’s (2008) study is one of its kinds that was conducted in a radiological science workplace consisting of four generational cohorts or age groups with distinct attitudes, values, work habits and expectations. This study provides current managers with a framework that enables them to accommodate most of the motivational needs of such diverse workforce. According to Chew and Relya-Chew (2007), radiology specialists are self-motivated individuals with high levels of intrinsic motivation. Although radiological sciences professionals experience other motivational factors such as high pay package, hygienic work conditions, job satisfaction, growth etc., it is important that their intrinsic motivation is nurtured constantly. Kalar’s (2008) study explains how intrinsic motivation of these RS specialists can be nurtured.In fact, Kalar’s (2008) findings related to motivating factors to each of these groups can be related to Vroom’s Expectancy theory. This theory proposes that an individual’s motivation depends upon the belief that his/her efforts could lead to high or better outcome and that these outcomes can lead to the achievement of desired goals. In this theory, three major factors of motivation are pointed out: expectancy, instrumentality and valence.
