Oftentimes we opted into quantity than quality. Productivity is relatively a friend of quantity. We want everything to have things be done in numbers, not giving emphasis on the quality rendered.
Often times our body reacted to the working hours and hard work spent inorder to get the productivity has been set for. You think we are mostly focusing to the value of quality to customer service we are rendering? Maybe not, because numbers has been set in our mindset.
This is where the work stigma kicks in. It would be nice it both quality and quality has been given an emphasis on customer service, everybody will be happy.
