Re: Pensionskasse changes their mind!
Could it be part-owned then by that company?
Whilst we were working there we were told the company had 'its own pension fund', that it was completely 'internal' and indeed the pension fund people are also treated as employees of the parent company, they have the same email addresses and are in the internal company directory. This pension fund covers people who work for a number of companies with the group, as well as pensioners who no longer work there.
Incidentally, this Pensionskasse has a disproportionately high number of invalidity pensioners (2nd pillar) on their books, due to the company constantly offloading long-term illness cases onto the IV!
