That memo was sent before the storm and before anyone was stranded. It was an attempt to prevent a future crisis. If your goal is to prevent a future crisis, alternatives to ramping up employee abuse 3 days before a big storm might be:
1. Hiring more people (more than 3 days in advance).
2. Paying people more so they don't quit.
3. Giving people paid sick time and not threatening their jobs when they take it so that they don't come to work sick and get a bunch of their colleagues sick.
4. Selling fewer tickets and running fewer flights if you don't have enough capacity to support the current workload.
