Not much you can do. The alternative is bankruptcy that does a similar thing to workers. But it at least doesn't let the company make blatant lies of a PR statement.

The main thing to do is make it so you can't just lay off people as easily as you can in the US for pretty much no reason. But it seems workers are still too divided to really come together and achieve such 9initiatives. Be it unions, pressuring their governments to make new laws, or simply chastising and boycotting companies who engage on such actions.
