Ask Bassa for all the legal options available to the company in the event you go on strike (or even threaten to). They would be being totally irresponsible not to fully inform you of the potential consequences.
When Balpa were in dispute over Open Skies, they sent out detailed information on the legal ramifications so that members wouldn't be voting for a strike without understanding the consequences of a strike vote.
Demand such information from Bassa! Do you think they'll be honest and up front? Course not.
