It’s easy to get comfortable around co-workers and share a little too much about yourself, but remember that there are things you should keep private to remain professional:
Your religious views. Religion is an emotional subject. If you ask questions or voice religious opinions at work, your co-workers may feel like you’re being unprofessional or even harassing them.
Your political party. Like religion, politics can be emotional.
Your social media statuses. Everything online is potentially visible to anyone, and anything you post can be used against you, and possibly could get you fired.
