The leader always calls me and sends messages. What should I do?

Speak out directly, be honest and self-interested, so that you won't stay in the end. Avoidance will only make some people shop more, because people always have the idea that silence means acquiescence. You have to do this for your family. You should grasp the rhythm and don't offend people. After all, he is the leader, but if not, you will have to change your job.
