Sadly Microburst IB pilots have been crying wolf and disrupting Spanish pax for years. A combination of the worst economic outlook for generations and the implementation of European laws has meant that employee protections have been vastly diluted. The low hanging fruit is being picked. One only has to read the newspapers to see that this is only the start of changes to come in Spain....
I don't believe that there will be much support for IB pilots from anyone in Spain. That along with the aggressive IB management leads me to think that SEPLA are unlikely to win this one. There is a saying that says we end up with the management that we deserve. I can't help thinking that the IB pilots have brought this on themselves.
