Here is the problem. "Unions are asking for increases in wages, money to fund pensions and job security."

- Wages = Autonomous ships will replace the majority of these jobs in the coming years meaning lower prices for everyone. Overpriced union labor is going away. It is inevitable. Resistance is futile.
- Pensions = Should all be on 401k retirement plans immune from raiding, best deal for companies and workers. Making the workers part of the plan.
- Job security = See Wages above. 

Enjoy it while you can as change is coming.
