If you get a new job these are rules you have to observe to ensure that you start work smoothly and have the chances to advance as quickly as possible;

- Avoid Scandals; Nothing will pull you down or even terminate your job appointment as quickly as office scandals. Steer clear from financial, sexual and ethical scandals. When you are due for promotion these are the things that count in your record so it is important that your work history be free of any such scandals.

- Keep Your Ears and Eyes Open and Your Mouth Shut: This is a commonsense advice for any career person who especially is starting work in a new environment. Learn all you can about your new place of work and only speak carefully lest you hurt some big ego or the other.

- Be Friendly to as Many People as Possible but Don’t Join Office Cliques: Depending on the organization you are working with when you join any organization you may observe various cliques loyal to certain individuals in the office. You will be tempted to join cliques and begin office politicking as soon as possible but that will be a mistake on your side especially as a new person. Be friendly to all, sympathetic to all but never join in petty office politics. Your major goal shall be to impress your supervisors and department heads.
