However, it is typically more of an issue particular types of industries, for example close protection operatives, security guards, bailiffs etc where conflict management is a central tenet of the job. Conflict management might also be more of an important skill in industries where employees are working in close proximity, such as in a maritime context (specific maritime training might be useful here.)
