Employments endpoint status changes

Hi Forum,

I am currently building a Power BI reporting solution based on the Personio API and I have a question regarding employee/employment status history.

In the Employments data, I can see fields such as the employee status (for example ACTIVE or LEAVE). However, it seems that the Employment entity only stores the current state and not historical changes.

I tested this with an employee whose status changed from ACTIVE to LEAVE. I expected that this would create a new Employment record (or some kind of historical/versioned entry), but instead I only see a single record that appears to have been updated.

My questions are:

Does Personio overwrite the existing Employment record when the status changes instead of creating a historical record?
Is there any API endpoint or audit/history table available to retrieve historical employee status changes?
Is there a recommended way to reconstruct historical employee statuses for BI/reporting purposes?
Are customers expected to build their own historization/snapshot logic externally?

The challenge is that without historical status information, Power BI reports cannot correctly show the employee status for past dates.

For example:

Employee becomes LEAVE in January
API now returns LEAVE as current status
In Power BI, the employee incorrectly appears as LEAVE even for dates before January

Any guidance or best practices would be greatly appreciated.
