To avoid a serious faux pas - and possible career sabotage - stay clear of the following workplace sins:Stealing - Whether you think that the company "owes" you things like Post-its, pens and other office supplies, or you simply don't think it's a big deal, you should be sure about that in case your boss or co-worker catches you.
Blaming someone else for your mistake - It's dishonest, childish and tacky. Very tacky. Sure, having to admit you made a mistake is embarrassing, but not nearly as embarrassing as it would be to have to admit you lied about it or tried to cover it up.
Spreading gossip - Who knows why people get a certain high from hearing juicy gossip. Many of us are guilty of passing along at least a few rumors at times, but the more you can avoid doing so, the better off you will be. Try to avoid it. In addition, if you hear it, don't repeat it.
Calling in sick when you are perfectly healthy - If you wake up and just cannot face the idea of going in to work, there's no reason (unless this happens every day) you shouldn't give yourself a vacation, personal or mental health day. Nevertheless, calling in sick is not only irresponsible and insensitive to the co-workers who have to cover for you, it could also be grounds for firing if you're caught.
Or showing up when you aren't - The admiration your co-workers show you for coming in to work despite having the flu will be short-lived: It won't take long for those around you to tire of hearing hacking, sniffling and coughing coming from your desk, nor will they appreciate being exposed to your germs.
Abusing office technology - This includes (but is not limited to): spending a significant amount of time on personal phone calls, e-mails or instant messages; using office time to type and print out the pieces of your screenplay; going online to catch up on last night's episode of "My Life on the D List"; and using the office printer to make the invites to your holiday party.
Getting too comfortable - Dressing professionally is just as important as behaving professionally in the workplace. No matter how long you've been with the company, how "cool" your boss is, how much sleep you got the night before, or how cold or hot it is outside, you should always maintain a clean, workplace-appropriate appearance.
