Does More Internal Hiring Mean Better Career Growth?

More internal hiring can mean better career growth when employees gain new responsibilities, support, and a credible route to advancement. The share of vacancies filled internally cannot tell you whether opportunity is broadly available. Employers also need to see who gets those roles, who takes on extra work without a move, and what happens to their previous jobs.

At BambooHR’s HR Virtual Summit 2026, Brandon Welch and Erica Wallace discussed an unusually still labor market. Welch warned that low turnover can conceal capability gaps. Wallace described high performers who stay but cannot move up, while work changes around them. Earlier in the summit, BambooHR CEO Brad Rencher told attendees that more jobs were being filled by moving existing employees.

The BambooHR State of Hiring 2026 quantifies that shift in its own platform data: internal hires accounted for 51% of recorded role fills in 2021 and 62% in 2025. That is a change in the share of fills, not proof that most employees advanced or that internal openings increased in absolute number. It makes the question of who benefits more urgent.

What does an internal hiring rate measure?

An internal hiring rate measures the share of filled roles taken by existing employees. It says where successful applicants came from; it does not show whether the move was a promotion, a lateral change, or an assignment that improved the employee’s prospects. Nor does it describe employees who wanted a move and never received one.

BambooHR’s 62% figure spans its customer organizations across countries. Some may have strong career pathways; others may be relying on familiar staff while external hiring slows. The aggregate cannot distinguish them. A company should inspect its own moves by role, level, department, and employee group before claiming that a rising internal share demonstrates healthy mobility.

Our article on specialist and management career paths considers one route that may be missing: advancement for people whose best contribution is specialist work. Counting promotions without checking the available paths can make a narrow ladder look generous.

How can employees be busy while careers remain stalled?

Employees can take on more work without receiving a clearer role, new authority, or support to develop. Welch described silent workload growth and roles drifting away from their original design. Wallace warned that people in entry-level positions can lose chances to progress when turnover is low and few openings appear above them. These were practitioner observations in the talk, not effects measured by BambooHR’s internal hiring figure.

Consider a strong employee who keeps absorbing projects when vacancies are left unfilled. They may be gaining valuable experience. They may also be performing a larger job while remaining at the same level, with no time to learn the skills required for the next one. Ask what changed in their duties, who owns the decisions, and whether the extra work is recognized in their development and pay.

The reverse can happen when a company fills a role internally but leaves the employee’s old responsibilities behind with their former team. One person moves, while several others inherit work without an explicit plan. A mobility program needs to account for both ends of the move.

How can an employer test whether internal mobility creates opportunity?

An employer can compare internal applications, selections, promotions, lateral moves, and time in role, then ask employees what blocked moves they wanted to make. Separate employees who changed jobs from those who received a new title for substantially the same work. Review whether managers release strong team members for opportunities elsewhere, and whether openings are advertised early enough for employees outside the hiring manager’s network to apply.

Rencher’s keynote treated internal movement as a workforce planning question: changing work calls for deliberate capability development. Welch and Wallace supplied the warning about treating low turnover as a complete picture of health. The practical response is to connect the next role to real preparation: the project experience, feedback, and support an employee needs before an opening appears.

My colleague Guy J. Giguère wrote about employee confidence in leadership and the value of visible internal paths during uncertainty. A path earns confidence when people can identify a possible move and see how to qualify for it. A larger internal hiring percentage is useful only if those opportunities are real for more than a small circle of employees.
