Do you think that if you deprive the employee of the mistake, you have deprived him of learning? Why?

Thanks for invitation,

I do believe that, the most effective way to encourage employee to avoid repeated mistakes and improve his skills is to motivate him via scientific practical training / coaching in order to cover any gap in his unacceptable or weakness performance.

 employee must be have more experince to be not mistake by learning and years of experince

Thanks

No doubt yes !This is the rule of the life, no mistakes no learnLet him - her do mistakes but under your supervision
