Spend too much time on personal calls, social media and likes
Even if you work in a busy, bustling office, there's a good chance someone is keeping track of your work habits. If you are spending hours browsing on social media or chatting away on the phone, keep in mind that your co-worker or manager may be noticing that.
Furthermore, if you are using your office's network or internet, be wary of patterns that could get you into trouble.
