Looks like it stands for "Recursos Humanos" ("Human Resources"). Not sure why that becomes RRHH instead of RH, but maybe a Spanish speaker can pipe up. Is it common to duplicate letters for plurality in Spanish acronyms?

According to this random Spanish website I found and translated using Google translate, it's done for plural words.

https://definicion.de/rrhh/

From that page's English translation:

> Its correct spelling is RR. H H. With a point after the second R and one after the second point H, and a space between the first point and the first H.

"RRHH" being standard for plural acronyms seems sane to me. A bit verbose, but sensible and clear. This bit about "RR. H H."--with that exact spacing and punctuation--makes no sense at all to me. I'm not curious enough to investigate the logic behind that, though.

Not a native Spanish speaker but I believe so. For example, the United States are EEUU (estados unidos).

>Human Resources

"Resources" it sounds at least disrespecting if you think about it

Also worth observing that “Human” is an adjective in that phrase, not a noun.

It’s plurals. See also Estados Unidos (EEUU).

RHs would have been better.
