Protecting workers from violence and harassment: Quick tips and the four stages of aggression

A fast, calm, and practiced response to someone who is becoming agitated in the workplace will help prevent potentially violent situations from escalating. No matter who is displaying the abusive or aggressive behaviour, a customer, client, contractor, co-worker or supervisor, knowing when and how to respond can protect your team. 

Abusive behaviour is often triggered by stressors and intense emotions such as frustration, helplessness, fear, anger, or feeling overwhelmed. Front-line workers are most frequently affected. The most effective response is to remain calm, avoid confrontation, and focus on what the person truly needs—to feel heard, seen, recognized, and acknowledged.

There are four escalating stages of aggression your workers should know: early warning signs, hostile, threatening, and assaultive. Recognizing the signs of aggression allows your team to act immediately to de-escalate. 

Responding to the four stages of aggression

Stage 1: Early warning signs. Watch for fidgeting, pacing, tapping, crossed arms, and rude language. Coach your staff to:

  • Listen
  • Stay calm and maintain distance
  • Try to understand the issue
  • Ask for possible solutions
  • Avoid being dismissive

Stage 2: Hostility. The agitated person may have a raised voice, rapid breathing, a red face, and begin arguing with others. Coach your staff to:

  • Maintain a safe distance
  • Alert another staff member or manager
  • Stay calm
  • Ensure you have an exit route
  • Be patient and allow silence
  • Move the person to a quieter area if safe

Stage 3: Threatening. Signs include clenched fists, yelling, and/or waving objects. Coach your staff to:

  • Call for assistance
  • Increase distance (2 metres or more)
  • Stay calm and keep communicating
  • Don't physically engage

Stage 4: Assaultive behaviours. This stage includes physical attacks like pushing or hitting. Coach your staff to:

  • Defend themselves if physical aggression is imminent
  • Know that only workers with proper training should engage in physical intervention
