Some workplace problems could have answers that are useful only in that industry or answers that are useful to a wide variety of industries, as long as it still applies to the industry the problem occurred in.
Consider that if I asked a question about a problem in industry A, I could get an answer that applies to A, or I could also get an answer that applies to A, B, C, D, and E industries, but if I get an answer that applies to B and C but not A, then that's a problem. Industry A must always be inclusive in an answer addressing a problem in industry A.
Thus, I don't see this as a localization problem but instead more as a focusing point. Localization is really about those extremely rare situations that won't help a wider audience barely larger than just the asker, but industries are large; there are countless possible future visitors of just about any industry.
With that said, I support adding tags for other industries, but an answer should never be limited to just applying to industry A and no other. For instance, this wouldn't be a good comment for us to see:
Hey user, your answer applies to industry A and B, but the asker was asking about industry A!
That would not be good, IMHO. As long as the answer addresses the problem the asker is facing, then it should be considered a good answer, barring other issues.
Let's wait a few days to give others an opportunity to weigh in before retagging.
