#employee-onboarding

New employees are most vulnerable to quit within the first 18 months, with many leaving after just 4 months without proper support. Replacing a $60,000 employee costs $30,000-$36,000 when factoring in hiring, training, and lost productivity that takes up to 2 years to recover. Effective onboarding during the critical first 90 days dramatically reduces these costs.

Poor onboarding costs US and UK companies $37 billion annually because employees lack understanding of their jobs. SHRM reports 50% turnover within 18 months, yet structured onboarding makes employees 58% more likely to stay three years. The first 90 days determine long-term retention. Georgia State research shows this probationary period is critical for building rapport with company and coworkers.
