Onboarding Importance

Executive Briefing
Beyond the Introduction: How Employers Drive Long Term Retention
Date: July 2025
Produced by: Shayne Simpson

Recruitment agencies create the spark by sourcing and introducing candidates. Employers, however, are responsible for sustaining the flame of retention. Culture, onboarding, leadership, engagement, and career development — not the initial introduction — are what keep employees long term.

Key Message

The Agency Role

  • Source and match candidates quickly.
  • Provide market intelligence and expectation setting.
  • Mitigate risk with temp-to-perm options.
  • Influence ends after day one.

The Employer’s Role

  • Culture: Positive cultures make employees 4x more likely to stay (SHRM, 2024).
  • Engagement: Engaged employees are loyal and productive (Gallup, 2025).
  • Onboarding: Structured onboarding boosts retention by 50% (HBR, 2018).
  • Leadership: People leave managers, not jobs; weekly 1:1s are critical.
  • Growth: 94% would stay longer if offered career development (Apollo Technical).
