I was working in an American company (I'm German) and had to learn to adapt to the style of being too nice (in my opinion). E.g. an "it might be better to do it like this", wasn't really meant as a weak suggestion, but a strong one. Something completely counterintuitive to my German mindset. I took it as a "might" and was met with negativity that I didn't exactly follow the "suggestion".
I much prefer language being direct at work. Treat the subjunctive as what it is: expressing uncertainty, not politeness.
I know however that many people, especially outside of Germany, prefer the indirect language, even though they learned to understand it with the same meaning as the direct speech.
