What Makes You Unprofessional?
Here are some things you could be doing that make you unprofessional.
1. Profanity. Every once in a while isn't too bad, but don't drop those f-bombs every time you speak to someone.
2. Being Late. This can show a lack of respect.
3. Being flaky. Saying you'll do it, then don't...
4. Overpromising. Before you say you can do it, make sure you can actually make it happen.
