About qualifications, skills and expertise in relation to language skills... knowledge and expertise are not necessarily judged on the same scales of importance (so to speak) as language skills. These two sides of the coin may BOTH be required, in equal measure.
Just as an example - my job, whilst it does require expertise and also a lot of customer contacts, is not something for which qualifications as such would play a
massively important role. Obviously you do need to be in the know of what goes on in the field, you need to know the substance of your work, and in fact knowledge of
English is another fairly important asset.
That is, even if you do need a certain level of experience and know-how -you do not need to be an Einstein to handle the
substance of my job (my friends are nodding their heads somewhere

) - this fact remains:
regardless of your skills and qualifications you simply could not survive in this job without fluent Finnish (and I'm making a clear distinction here between '
quite fluent non-native language speaker' and '
1000 words fluency').
This is not being big-headed, it is a plain and simple fact. The thing is, English is required but that
alone will not get you anywhere. Not only in customer contacts, but also in keeping track with the field, communicating with vcolleagues, reading circulars, publications, memos, presentations... you know what, they're in Finnish mostly, and will continue to be. Sorry to say, but more or less the only people that move about in the same offices and who do NOT absolutely need Finnish in their job... are a few of the IT support guys (sic!) and ... the cleaners.
Yes, this is just one example among the many, but still I'm afraid the same is true of
many other employees.
BUT my main point after this would be that unless we can assess the situation realistically, without too rosy-coloured glasses, there's little hope that we could come up with answers and solutions of any relevance to the real world as we know it either.
