In Austria there are government officials who cannot be fired. Usually, they get this status after serving a certain amount of time.
In German this practice is called Pragmatisierung and seems to be specific to Austria.
I am looking for a close-enough English equivalent.
Example of usage in a sentence (
XXXX is the adjective I am looking for):
A XXXX government official cannot be laid off.
The only word that comes to mind is tenured. The problem is that tenured seems to be specific to academia, whereas Pragmatisierung is not industry-specific (all sorts of civil servants, not only teachers, can get this status).
