Managing behaviour has always been a vital part of youth work and helps to protect the safety and wellbeing of young people. Based on interviews with 20 young people and 15 youth workers in New South Wales, Australia, a range of strategies used by youth workers for managing behaviour are identified that could be placed on a continuum from coercive to non-coercive. Coercive strategies included physical restraint, calling the police and exclusion. Non-coercive strategies included building relationships, using group dynamics, negotiation and mediation, establishing clear boundaries and structure, and preventing problems from escalating. Potential principles for behaviour management in youth work are identified that emphasise the importance of building good relationships with young people, using non-coercive strategies, assisting young people to learn from their experiences; creating a positive, welcoming environment; operating from a position of power-with; and having adequate resources and staffing levels.
