The company has already started applying its new bidding rules in SJU. And the new rules violate the principle of seniority in favor of what the company wanted which was putting "the best people where they wanted them". So if two people have the exact same qualifications whether its taxi, hot bond, sheet metel, avionics that management feels they need then yes the senior man gets the spot but a Jumior man may get day shift over a senior man if the company deceides they need certian qualifications for that shift and they decided to send the Junior man to get trained.
These guys really have no idea what they voted for do they?
