Boss Warning Signs: If your boss shows these signs, your job could be at risk. Here's what you should never say to your senior.

There are times at the office when you work with complete sincerity, yet your boss fails to offer the expected praise, promotion, or positive rating. The reason may not lie solely in your work performance but in a deteriorating professional relationship with your boss. Bosses often do not express their displeasure in so many words; instead, changes in their behavior signal a growing rift in the relationship.
