Do Asians too much care on respect (age) which becomes barrier in workplaces?

Answer 1

Sometimes. But usually people will tell if anything's wrong and compliment if anything's right.

Answer 2

The main place that age becomes a barrier in the workplace is in professional sports. Psychotherapists, for example, become more valuable with age because of experience and further learning. Sales people become more proficient with age as their experience adds to their repertoire. Just a few examples. Lastly, older people are often better grammatically than younger people.
