Things are more complicated than they seem.
Unless you've spent time working with Jet or at least for an airline in India there are a lot of nuances to the management/pilots relationship there that you'll be missing. This situation is certainly nowhere near as simple or obvious as either party wishes to portray it.
It's true that the company has changed things such as the rules of progression on the Indian pilot group several times without sufficient mutual negotiation. However, it's also true that a goodly number of the pilot group routinely take individual actions that would be firing offences in most airlines elsewhere but that go undisciplined at Jet and similarly at other airlines in India.
From time spent in India my observation would be that pilot/management relations there can't be directly compared with what is considered normal in the rest of the world. The costs of open labour warfare, however, are about the same. Hopefully the cooler heads on both sides will prevail sooner rather than later, before they do each other irrepairable damage.
