I live and work in NL but a lot of companies have international employees, which means the going language is English. But it's English where nobody speaks it natively, so you end up with this kind of expat-English.
Companies like that should invest in either weekly class-based lessons, or mandatory one-to-one language classes through e.g. online. Spelling, grammar, writing and speaking practice, as well as culture classes.
And related to the article, typing classes. I've encountered multiple people now working in IT, whose job is reading and writing (code, documentation, emails, whatever) who cannot touch type. I don't think not being able to express oneself on a keyboard in a quick way is acceptable anymore. I can recommend typing.com, five minutes a day at least, it doesn't take that long to learn touch typing.
