As a subordinate, when you meet a leader, you should take the initiative to greet the leader. If the distance is too far to make a phone call, you can look with your eyes. When the leader meets your eyes, just nod. If you get along closely, you can say hello in polite language. In addition, in the process of dealing with leaders, you should always remember to use polite expressions to let leaders feel your respect for them.
On the contrary, if you don't use polite language to the leader, it will make him feel that you lack self-cultivation and don't know manners. In addition, in the use of polite expressions, only proper use can make people feel comfortable, so we should avoid improper use of words.
