I don't think the ability to understand the accents of the people you may interact with at work is an unreasonable baseline job requirement, at least not these days of very diverse teams. Many people have to learn an entire foreign language (English) as a job requirement! If I went to work at a German company, I might be both expected to learn German fluently and be able to understand regional accents, too.
