Which of the following is NOT a method of employee motivation mentioned in the text?

Job fulfillment is not typically categorized as a formal method of employee motivation like the other options listed. The concept refers more to an individual's sense of satisfaction and completeness they might feel regarding their job. In contrast, methods like job enrichment, commission, and bonus plans are structured approaches aimed at increasing motivation through tangible rewards or enhancements to job roles.

Job enrichment involves redesigning jobs to enhance employee satisfaction through increased complexity and responsibility. Commission provides a financial incentive based on performance, thus motivating employees to achieve specific sales or productivity targets. Bonus plans are additional compensation strategies that reward employees for achieving goals or milestones. All these methods aim explicitly to motivate employees through clear systems of recognition and reward, while job fulfillment is more subjective and individualistic.
