What are the main factors of achieving happiness in the workplace?

The main factors of achieving happiness in the workplace is team work.

Be happy and make happy !! *!*

"believe in everything is possible just required little bit more efforts, make easy rules of life and learn good things from others and ignore bad"

I can't really tell how can one person be happy at his workplace and be unhappy outside his work place.
With our misguided definition of time, we tend to believe that are our lives are divided into chunks more than as a continuous tape! our workplace should provide us with a friendly environment were we can work, interact, feel our value, feel appreciated, and get compensated with an outcome that can deliver a satisfactory life.
If you break any of these, everything breaks.
we spend more than1/3 of our day at work and1/3 sleeping, so if you're not happy at work that means you spend more than half of your -waking- day feeling unhappy! Friendly environment.
Friends at work more than colleagues.
Management appreciation.
Satisfactory salary.
High improvement potential.
I think if we manage to collect all of that we'll be happy.
