Do I have to send text messages to my tutor on New Year's Day and Spring Festival?

Do I have to send short messages to the leaders on New Year's Day and Spring Festival? Generally speaking, it is a blessing to send text messages to leaders on New Year's Day and Spring Festival, and some people will give gifts to leaders on this festival, which will make them feel good about you. Work smoothly next year or get a promotion and raise. If this kind of thing must be done, I personally think, er, it is not necessary. Need personal will, because this kind of salary is a promotion and salary increase. This is not, um ... because, um, on New Year's Day and Spring Festival, employees are not obliged to send them to their leaders. For new blessings or benefits, well, first, if you want a promotion and a raise, you can work hard and be careful, and then it will be beneficial to the company, and the old boss will give it to you. Well, a certain reward will encourage you to make persistent efforts, or set an example for others and then encourage others to drive.
