Ever wondered why people act in certain ways? In a work context you might have wondered why;

Sally didn’t hand that project in on time, even though she knew how important it was...

Bob got into another heated argument with a contractor even though he has been spoken to in the past about his communication skills....  

Why Tim just can’t seem to put his dirty coffee cups in the washing machine instead of leaving it in the sink....

Well Sally, Bob and Tim all exhibit behaviour because of antecedents that occur first. Let me explain a little further.
