People’s behaviour in the workplace is affected by the characteristics of the business or organisation for which they work. For example, a new starter will quickly learn the ways of behaving that are considered normal from their fellow workers and supervisors. Workers and work groups also respond to the messages and cues they receive from managers and supervisors, though not always in the way intended. All these things reflect the culture of the organisation. To manage health & safety effectively it is important to consider how all these organisational level influences affect human behaviour.
