Secondment

In some jurisdictions, [e.g., India] such temporary transfer of employees is called "on deputation".

The employee typically retains their salary and other employment rights from their primary organization but they work closely within the other organization to provide training, a liaison between the two companies and the sharing of experience.

Secondment, sometimes referred to as employer of record (EoR) or professional employer organization (PEO), can also be used to help organizations hire during a headcount freeze.

[citation needed] For example, statisticians from the British Government Statistical Service may be assigned to the Full Fact charity, to check statistics presented in political campaigns and the mass media.
