Do you want to invite the whole company to dinner after marriage? I've only been a girl for half a year, and my colleagues have a normal relationship. Our company has 10 people and 3 departments.
Colleagues are always colleagues, so it is best not to invite them. Just send a wedding wish. No one can guarantee that they will always be in the same company and pay attention to reciprocity. Today, he will give it to you. If he leaves, can he find you at random? Besides, can the boss expect the whole company to attend the wedding and delay his work?
