Employees who are satisfied in their jobs are more
productive, perform better, and are more willing to go the
extra mile when a situation calls for greater effort or
longer hours. Those who are unsatisfied are more likely to
have undesirable behavior such as slacking off, leaving
early and even stealing from the office. We all want our
employees to exhibit the “good" behavior, so what can we do
to ensure their job satisfaction? According to a recent
survey conducted by the Universities of Florida and Michigan
State, how supervisors treat their employees plays a huge
role in how the employees feel at work, and consequently how
they behave.

“What can make the most difference are supervisors who treat
their employees with respect, he says. Supervisors who are
rude or mean to employees increase workplace problems
because employees become frustrated and angry.
"When you are treated in a fair, just manner, you're going
to be more satisfied with your job, which is going to reduce
the behaviors," Ilies says."

It is critical for leaders to respect their employees, and
to show that respect through appropriate displays of warmth,
compassion, humor, concern, interest and understanding. Some
call this the “humanity" factor. I refer to it as “agape"
which is a word for love that translates to loving everyone
simply for the sake that they are human. I repeatedly tell
leaders that their most important step in leadership is to
love all of their associates. Treating them with love and
respect does not mean crossing the line and becoming their
“buddy"; it means setting a tone that will foster trust and
loyalty. If you treat your associates with genuine respect,
they are much more likely to reward you with the attitude,
behavior and performance that you desire.
