Answer:
Herzberg's two factor theory
Explanation:
Herzberg's two factor theory differentiates between:
i) Extrinsic rewards also known as hygiene factors - Where employers do not provide expected extrinsic rewards, employees will be dissatisfied and demotivated. Such rewards include salary, adequate work conditions and job security and are typically expected of any employer.
ii) Intrinsic rewards also known as motivators - represent additional benefits other than those that are typically expected of an employer. Such benefits include recognition, personal growth, challenging work etc. and strongly influence performance of employees.
