Is it good morning or evening to send greetings to the leaders and change jobs?

This greeting was sent in the morning.

It is most appropriate to send greetings to the leader in the morning, because he will start his day's work in the morning, and the workload is very heavy every day. At the end of the day, he will be overwhelmed by something. If you send him a message at other times, he may turn a blind eye, so sending a message in the morning is the most appropriate.

When he is not off work, he will find a message on his mobile phone, and he will easily remember the sender, which is also conducive to developing some cooperation with him in the future.
