"Reward or Punishment" what works best in encouraging employees to be more productive?

Rewards and discouragement. No punishment or sanctions are good measures in HR management. If a staff member fails to turn up on time several times, set up a brief meeting with a Staff Consultant to find out the causes and provide ideas to solve it..should be enough. Staff needs no police behind them, they need leadership, guidance and opportunity to adapt properly. If you allow this and keep on providing the rewards, people will soon fit in.    

Rewards & appreciations which can increase the spirit of  work & dedication can make him more loyal to the  management & productivity will improve.

It is best to follow the methodology of awarding bonuses, awards or implicit penalties that are implicit or concrete because they have a catalytic role that is stronger than the actual physical yield.

Moral motivation is the employee's appreciation and respect and appreciation of his problems and also give the employee diligent material rewards in addition to career promotion and training and development

A rEWARDS COUPLED TO PERFORMANCE and Punishment as to not give expeted increase for non satisfactory performnace when a performance appraisal has been done

Both choicesEvery place has a place, in other words, if the employee is better, we have to compensate him, but if he misbehaves there must be punishment.

firstly you need both, but the tip is how to use it, you have to balance both of the side, always you need to motivate them to get the rewards, and avoid talking about the punushment all the time, but when it requires. only, be positive.

but some times need 

Thanks

Both .....

It depend on situation itself.

Rewards and appreciation are enough with COC on asic violaions.

Thanks for invitation,

I do believe that matter has to be considered by management case-by-case, depending on the benefits that are exists or to how far the policies and procedures are violated.
