What is professionalism?

In some jobs your expected to roll up in a suit and tie and in others it would be frowned upon if you did. Just try to wear a suit a Google or Facebook and you would be so out of place it would be unreal. But that does not mean their staff are unprofessional.

So What is Professionalism?

Does it vary by industry or sector?

Is what I think professionalism is vary from what you think and vice versa?

The answer to both these questions I tend to think is yes. But some things are seen as unprofessional no matter what sector you are. Like any of the following:

1. Been rude  to customers (It does not matter who you are or what function in a company you preform this is just a hard and fast rule in my book)
2. Dressing incorrectly for you job Trainers to work when every one else wears a suit or such like you can dress to smart but under dressing/incorrect is unprofessional or is it? 
3. ETC.

Just been bad at your job does not make you unprofessional or been good at it make you Automatically make you professional. It just helps
