the BenQ employees here in Munich were not expecting this.
They should have been. It wasn't really difficult to see it coming.
The same thing happened with the Sony R&D site in Munich. After the JV with Ericsson they only kept the Munich site going for about a year before the Sony Ericsson management decided to shut it down.
The BenQ employees can probably take some comfort in the fact that the German employment laws will see that they get a nice redundancy payoff, assuming their
Betreibsrat is any good. All those dead-wood Siemens middle managers who would have been given the boot years ago in a UK or US company will probably make a tidy sum out of it.
