If a group of workers cannot come to terms with their management, they should have the right to strike, transportation workers and public employees included. I find it hard to place my own convenience as a passenger above this right. Many other transportation alternatives are always available, even though not necessarily equivalent.
If the President can take away the right to strike by executive order, then why should he not have the right temporarily to nationalize the airline by executive order?

Oh No, we can't have that! Violates free market! So does the R.L.A. What's good for the goose is rarely good for the gander, and it's a myth that workers have much in the way of rights in this country.
