The Vietnamese have a phrase about the Japanese: one Japanese is like a mouse, but three Japanese is like a lion.
The Vietnamese are the absolute reverse. One Vietnamese is like a lion; you can deal with them one-on-one and you can trust them to do a great job.
But deal with a group of Vietnamese and you're dealing with socialism; they will sit around and nothing gets done.
The rhythm of work moves at its own pace. Work is a group activity. Co-workers talk, they play, they enjoy one another.
To wreak havoc on this family atmosphere in the workplace is to destroy morale, yet changes will have to take place and people will have to be trained if productivity and quality are to be enhanced.
