My thought precisely. It says a lot about him that he didn't seem to think that him learning Spanish was any part of the solution. Heck, if I were in his situation, I don't think I'd try for fluency; I think I'd just try to get a basic vocabulary together ... and I'd find someone who could fill me in on the most common insult words. Then I'd practice. If he's really worried about employees being sneaky around him in Spanish, he could probably get away with mastering a few good boss-to-employee type phrases to use.
