Good timekeeping is one of the most valuable assets of a top office professional. You should always arrive 15 minutes early and take care of “opening the office/shop”. If you are prepared and ready, you provide a calm and welcoming front to your boss, staff and clients.
Every boss has a different set of requirements. The rules you have learned may be different from those of your new company. Observe or ask questions and adjust to new systems and formats. Where no systems exist, supplement your own but with sensitivity to the other staff.
Even in a small office there are people around you whose help you need and who need your help. Acknowledge all of the little people with words of thanks and small gifts. This will not cost you a lot of money but will certainly get you help when you have a big mail-out.
