Reread the comment chain, because I literally quoted a comment saying that repeatedly voicing your dissatisfaction to your boss can reduce the robust employment protections in some countries in Europe.
Where is "change in law" coming from? How could it possibly mean that in context?
Of course the meaning is "reducing the protections you have". And I'm challenging the notion that complaining or voicing dissatisfaction could do that in any European country.
Therefore I would like examples of countries where it is the case that simply complaining to your boss has any impact on protections you have.
