Rationale: In Herzberg's theory, only training is a 'motivator factor'. The others are all 'hygiene' factors: if they are inadequate, employees will be dissatisfied, but even if they are got right, they will not provide lasting satisfaction or motivation. Herzberg argued that satisfaction comes only from the job.
Pitfalls: Herzberg is frequently examined, and examiners are frustrated to see students get the basics of the theory wrong! Make sure you can sort the motivator factors from the hygiene factors.
