This paper (PDF file) gives the following example of a typical no-strike clause in a collective bargaining agreement in the United States (the paper is from 1984, so I'm not sure to what extent it reflects the current reality in the US):
The union agrees that it will not collectively, concertedly or individually engage in or participate, directly or indirectly, in any strike, slowdown, stoppage or any other interference with or interruption of the work or operations of the employer during the term of this agreement; and the employer agrees that during the term of this agreement it will not lock out any of the employees in the bargaining unit covered by this agreement.
What are some jurisdictions where this kind of clause would be legal/illegal?
If the scope of the question is too large, I'm interested in particular in European Union countries. The question is simply for my personal culture relative to workers' rights.
Thanks,
