Flipflapflop
Those pilots in the U.K. Are employees of OSM, they pay PAYE tax & NI and have the same employment rights as any other person employed in the U.K.
The result of Norwegian not likening someone and wanting them off the contract ( as some on this forum like to suggest) would be interesting as without grounds for dismissal OSM would likely find themselfs in an industrial court with BALPA and the law on the employees side.
OSM recognised BALPA some time back so union membership is not a problem.
