No, they won't. Because they know, even if there was a somewhat organized thing, that it wasn't the reasons for the cancellations. The sick rate for captains was 8% higher than the average, for FOs around 5%. That is well within the normal day to day variations. And the company did cancel flights where the crew was already on board and preparing to fly, for no apparent reason.
Already six months ago they knew that they won't have enough pilots for the september schedule, and that got worse three months ago when they decided to go from 60 to 75 minutes check in time and from 30 to 45 check out time starting 1st of september, which increased the crew demand considerably.
Apparently a huge operational problem was covered up by having a convenient scape goat.
