A sign that you have a negative workplace culture is dishonesty. Just listen to how much dishonesty there is where you work. You can work hard and get great results and still be surrounded by dishonesty. Dishonesty creates a culture of mistrust, negativity, low morale and crushed self-esteem. You can also disengage and remember that you have laughter and positivity with your small work circle who will actually tell the truth when dishonesty occurs. True "friends" stand up for one another, especially when one is being attacked for speaking the truth. Those who never have your back are simply coworkers.
