PAP's Murali is ethically bankrupt!
What Murali should have done if he was a moral person would be to say that if he does this as a Part Time Job, he should have in the very same breath said he will take only partial salary. That is fair and morally upright thing to do. For example, if he says he will discharge his MP duties for only 10 hours a week, then, he should just say that he has voluntarily turn down $13000 in pay and accept only a $4000 salary. In this way, these is some justification for telling everyone that he will work only part time for them.
