I often ask clients to reflect on their working life and identify the number of supportive, inspirational role models they had worked with and learned from. Mostly they identify one, maybe two people and typically go on to count and identify dozens of the other kind – unprofessional colleagues and managers who made their lives a misery, treated people poorly and created a workplace that was stressful and unpleasant. Awful that it may be, we can still learn a lot from unprofessional colleagues and managers which is, what not to be like in our own business management practises.
