This chapter explores the contribution of organisational, operational, and personal stressors to police misconduct, situating stress as a central but underexamined driver. Policing is an inherently high-stress occupation, characterised by exposure to trauma, bureaucratic pressures, public scrutiny, and irregular hours. This chapter discusses how job demands, workplace, and life-course stressors interact with psychological distress to erode decision-making and ethical resilience among some officers who commit particularly serious misconduct. Using a qualitative analysis of dismissal records, the study identifies five major stressor classes linked by officers to career-ending misconduct: financial pressures, declining health, duty-related stressors, personal relationship breakdowns, and adverse interactions with colleagues. Officers frequently positioned these stressors as mitigating or explanatory factors for their misconduct. The findings underscore that misconduct often arises, not from isolated individual failings, but from the cumulative effects of chronic stressors embedded in police work and life circumstances. The chapter concludes by advocating for prevention models that integrate mental health support, organisational reforms, financial and family assistance, and stress awareness education, reframing misconduct reduction as both a welfare and accountability priority.
