Joining a new office always bring a pot of mixed feelings with waves of emotions and thoughts in mind. You might have got a higher position in the new office that pours joy along with some more responsibilities.
Do you feel as your older co-worker is interfering in your every task like the darned parents with an attitude of saying and I have done this in that way? You might be sharing the same Office Desk and storage space, which too bring some tough situations. If yes, that may be an annoying and unpleasant experience.
Try to find out the problem
Do not start reacting at the beginning. Observe their behaviour for you and for the rest co-workers. If it is same for all then you can ignore the things and continue your work in your way with the smarter discussion. However, if involves only you, then find out why it is happening. Do not fear to accept if you are the wrong t any point or they do more care for you. You can also have a talk with them alone.
Remember do not confront them in public as they do not want any bash on their self-respect. You can discuss your feelings and their intention one-on-one to get over the problem. Be polite and consider they are much older and experienced than you, so do not cross the line.
Be polite and involved
Though it is not your fault, you can bring the change. Address every co-worker with a positive attitude and productive manner. It is worth to be respectful to others so the people do not get a chance to blame you. Create your attendance at office space more respect-worthy.
Do not let your work affect
Whatever the problems are among you and your senior co-worker, do not let it affect your work. Do not stop talking to such people if you are involved in the same project or required to have talk to complete the task, go for it. Do not mix the things; after all, you are there to work.
Talk to other colleagues
If the conditions get worse, you can discuss the issue with the other co-workers that can guide and resolve the problem. They are valuable as the Used Office Furniture, hence, may require polishing or special attention sometimes for improvising their behaviour and value.
