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).
