Not in so many words, but I'm sure
it's in there ... probably in Article 23(4) "Everyone has the right to form and to join trade unions for the protection of his interests.", right below 23(1) "Everyone has the right to work..." and the minefield of 23(3).
But there is always 29(1), which
Spiderman said best, and I always tell my programmers: "With great power there must come great responsibility."
More to the point -- lets keep politics out of Chief Delphi.
Good luck to everyone in Wisconsin getting through this.
