How odd that it seems to be acceptable to some that they should buy continuation of their jobs and deny themselves elements of flexibility. It is like being indentured.
If one were self employed then I could imagine that preparing oneself to undertake a contract would be accepatable practice. However, I don't believe that that should apply to employees. Nice work, if as an employer you can get away with it, but I believe that it does abrogate some of an employers responsibilities. Of course it is morally indefensible, but why should that worry MOL?
