Your employer might not spell it out to you, but I will. Bosses and managers biggest complaints about employees are the following:
You are Not professional if you are late! There is no debate here. I have worked with people who swear they are super professional but are notoriously late. You are a waste of time. Time is something you cannot get back. You are also disrespectful. There is no other way to put it, because your lateness has a domino effect and ultimately affects many different people’s days. You are a waste of money and a liability. I will give you a 15-minute grace period, one time every 3 months. After that, you are no longer worth my time or energy.
You are Not professional if you do not keep your word! Your word is all you have. If you give deadlines and do not meet them or over commit yourself, you should have thought about that before you opened your mouth. If you lie to me once, after that nothing you say will I believe.
You are Not professional if you aren’t dressed right! Dressing right for a job isn’t a matter of opinion or have and have nots. It’s a matter of being well groomed and presentable.
You are Not professional if you let your personal life interfere with your job! I do not need your love life interfering with the office. Your lovers quarrel should never make it to your place of business.
You are NOT professional if you spend company time tending to personal matters. Paying bills, going to the cleaners, travel arrangements should never be made on company’s time.
YOU ARE NOT PROFESSIONAL IF YOU ARE ENTERTAINING OFFICE GOSSIP! (You are not at work to make friends or talk about people. DO YOUR JOB AND LEAVE.)
Basic common sense will get you far in life!
