What belongs to the employees?
Just because there is an *S* at the end of the word does NOT mean an apostrophe is used. Plural does NOT use an apostrophe. POSSESSIVE tense does!
Rudolf Hess was the editor for Adolph Hitler’s biography “Mein Kampf”. That makes him the original “Grammar Nazi”.
It is truly stunning how many apostrophes are thrown around these days! Here, there, everywhere! If in doubt, thrown in an apostrophe, just in case lol.
