Create Job requisition from position - multiple locations

Summary:

We are creating are job requisitions based on positions.

Yet, sometimes it happens to have 1 position (1 headcount) for which we are open to hire candidates in multiple countries.

This means we might have multiple posting locations and multiple work locations, yet one single legal employer.

Also, although we add multiple posting locations, the job boards (Indeed, LinkedIn) are only using the primary location.

I am looking for some advice on how to best manage these cases. How are you usually handling such cases?

Thank you,

Ana
