Definition
Internal mobility means filling a role with a current employee: promotion, lateral transfer, change of team or occupation. It often shortens ramp-up time, since the person already knows the organization, and it offers career paths that help retain staff.
Useful formula
Internal mobility rate = roles filled internally / total roles filled × 100.
Illustrative example: of 25 roles filled in the year, 6 went to existing employees. The internal mobility rate is 24%.
Key takeaway
- Post roles internally with the same criteria as externally, so the process stays fair.
- Answer unsuccessful internal candidates with a specific reason and a development plan: a silent rejection internally often costs a resignation.
- In Ontario, roles advertised internally only are excluded from the 2026 public job posting rules.
- Track the retention and performance of people who moved internally, and compare them with external hires for the same roles: it shows whether internal mobility actually pays off for your organization.
