Yes, the SAS tory is sad, but it is the typical divide and conquer tactic. SAS has been playing the diferent work groups against each other for years, now mind you, due to three different countries being part of it, there are three different Unions for most workgroups.
Lindegaard is playing hardball, but I am not sure he could actually replace say danish workers with swedish, while they do have the right to work in Denmark, it would do very little for relations between the two countries. And it could force the danes to seriously reconsider having anything to do with SAS.
