In a storm you do not abandon the deck and call it leverage. A five-day strike in winter pressure will hit the frail first, and everyone knows it. I understand anger about pay and conditions, but duty does not vanish because negotiations are ugly. If the offer was poor, keep talking, escalate politically, bring in arbitration, do not walk away from the wards. Every cancelled list today becomes heavier ice tomorrow, and the ship does not care whose speech won the news cycle. Win the argument without freezing the passengers.
