The type of education in fundamentals that would allow users to flexibly switch between office productivity applications requires a fairly high level of abstract thinking. Not everyone has that cognitive ability. Some struggle with anything more complex than executing a set procedure and would require years of remedial education to break out of that mindset.
Maybe dont employ these people in positions that require a specific way of thinking then...
You're really missing the point. Most clerical jobs don't require that specific way of thinking. Major changes to office productivity applications are quite rare and it would be silly to hire for those jobs based on abstract cognitive abilities. Ability to reliably follow instructions is usually sufficient.
Until... you change the software.
