What is: Tenuki

TENUKI: An employee is not doing what he should do (he should be adding value, hataraki) because he is doing something else, so wasting his energy (ugoki)

Tenuki could be translated as ‘absence’; we would associate this with illness.
Here the employee is ‘absent’ doing his real job, because he is working (maybe sweating very hard!) on something that creates no value; a complete new perspective, isn’t it?
