Employee tenure is how long someone has worked for their current employer. It is a simple number, but the way you calculate and read it changes what it tells you about retention, and several legal rules run on length of service.
| Measure | What it shows | Watch for |
|---|---|---|
| Median tenure | The middle employee’s length of service | Better than the average when a few people have decades |
| Tenure by role or site | Where people stay and where they leave | Small groups swing a lot |
| Share under 1 year | How much of the workforce is new | High numbers point to an early turnover problem |
| Tenure at exit | How long leavers stayed | Separates early quitters from long-serving departures |

A small machine shop has 9 employees. Their tenures in years are 0.3, 0.5, 0.8, 1.0, 1.2, 1.5, 2.0, 3.0 and 26.
The average is 36.3 / 9 = about 4.0 years, which looks like a stable team. The median, the fifth value, is 1.2 years. Four of the nine have been there a year or less.
The owner had been told the shop’s tenure was about 4 years and that retention was fine. The median tells the real story: apart from one long-serving machinist, most of the team is new, and onboarding and training are where the effort should go. She also checks her PTO policy, which raises accrual at 3 years, and finds that only two people have ever reached it.
Many policies use tenure as a trigger: higher PTO accrual after set years, a pay step at an anniversary, eligibility for a benefit after a waiting period. Each trigger needs a clear rule for what counts as service, especially for part-time employees, people on leave and rehires. Write the rule once and use it everywhere, so the same employee does not have two different service dates in two systems.
Recognize tenure on purpose. A short note from the owner at each work anniversary, or an announcement to the team, costs little. The work anniversary ideas guide has ideas that fit hourly teams.
A retailer rehires a cashier who left 18 months ago after 3 years of service. Its PTO policy raises accrual at 5 years, and its rehire rule bridges earlier service if the break was under 2 years.
Her service date is adjusted so that her earlier 3 years count. She reaches the 5-year accrual level 2 years after rehire, not 5. For FMLA, her earlier months of service also count, because her break was under seven years. HR records the adjusted service date in her file so payroll and scheduling use the same date.
Count the time from each employee’s start date to today, or to their last day for leavers. For a group, report the median as well as the average.
BLS reported a median of 4.1 years with the current employer for wage and salary workers in January 2026.
It depends on the industry. In many hourly jobs, two or three years is long. In some professions, ten years is common.
It depends on the rule. Under the FMLA, earlier service generally counts unless the break was seven years or more. Company policies set their own rules.
Usually from the start date, the same as full-time staff, unless a policy or plan counts hours of service instead. Write down which rule applies to each benefit.
It depends on the policy and the law involved. Some laws, such as the military leave law USERRA, protect seniority for time away, and company policy sets the rule for many other benefits.
