Benefits Tied to Tenure
Many benefits vest or increase with tenure: 401(k) matching often vests over 3-5 years, PTO accrual rates increase with years of service, sabbaticals may require 5-7 years, and long-term disability coverage might improve. Know your tenure to understand your benefits.
Career Planning with Tenure
Average job tenure varies by industry and generation. Millennials average 2.8 years per job; Baby Boomers averaged 10+ years. Neither is inherently better—but understanding your tenure helps with career planning, resume presentation, and negotiating when tenure milestones approach.
