When deciding whether to send an invitation, we should also consider the relationship between colleagues. If you have a simple relationship with your colleagues and don't have much friendship, it may not be appropriate to invite them to your wedding. If you have established a close relationship with your colleagues, it may be more appropriate to invite them to your wedding.
In addition, if you have worked in the company for a long time and have a stable relationship with your colleagues, it may be more appropriate to invite them to your wedding. However, if you work in the company for a short time or have an unstable relationship with your colleagues, then you don't need to invite them to your wedding.
In short, when deciding whether to send an invitation, you need to consider your own situation and preferences and the relationship between colleagues. The final decision should be based on your personal situation and decision.
