Is Static Method safe in job system??? (Multithreading)

Unity Engine
1

So in the job system document.
https://docs.unity3d.com/Manual/JobSystemTroubleshooting.html

We are advised not to use static data.
But is static method also prohibited
or it is OK to use static methods
if I don’t access any static data from the static methods?

According to this discussion, it appears OK but I don’t know whether Unity3d has a different condition.
