In this situation, it is important to approach the matter with understanding and respect for your colleague's personal boundaries. It is possible that your colleague may have their own reasons for not accepting your follow request on Instagram. They may prefer to keep their personal and professional lives separate, or they may simply choose to keep their social media circle small. It is also possible that they may have missed or overlooked your request.Rather than directly asking your colleague why they haven't accepted your request, it is usually best to continue behaving as you normally would in the workplace. It is important to maintain professional boundaries and not let this situation affect your working relationship. You can continue to have friendly conversations and interact positively with your colleague.Remember, everyone has different preferences when it comes to social media interactions. It is essential to respect their choices and privacy. If your colleague eventually accepts your request, then it can be a pleasant and welcome surprise. However, if they never accept it, it is important not to take it personally and understand that it does not affect your professional relationship.Focusing on maintaining a positive work environment and building strong professional relationships based on mutual respect and trust is crucial. As time goes on, you may develop a stronger bond with your colleague that extends beyond social media interactions.
