Does it constitute a crime for a resigned employee to harass and abuse his boss many times and send mobile phone text messages to attack and abuse him? What kind of laws should they be bound by?

You need to tie the bell to solve the bell! There must be something unsatisfactory or unknown in this! It's a pity that this abusive person is mentally ill! Otherwise it wouldn't be like this! Many times, many bosses owe scolding! It's just that most people choose to let nature take its course, but these people are always psychologically uneasy, and it will fade after a long time! I also want to find fault with the original boss, not buying social security, and maliciously defaulting on wages; A person has to do the work of three people, and a colleague is his relative. He's always messing with people when he has nothing to do, and he doesn't treat people like people. He also asked to get off and take the bus, and he was not allowed to take a taxi after a long walk! Ha ha! Complain! Suggestion! Let's calm down and talk and make up for what we owe! It is fundamental to spend some money on a meal to solve the problem!
