Biases are an integral part of human nature. At the workplace, human biases can become toxic or lead to discrimination, creating a stifle environment and impact productivity and profitability.
Biases work at two levels- conscious (those that we are aware of and can work towards overcoming) and unconscious ( those that are a part of our subconscious and surface from time to time). The latter often goes unnoticed and unchecked to the person displaying such biased behaviour.
