If you take the "law" aspect out of the equation, this pension question seems to me like a gross violation of the basic employer-employee relationship based on respect, fairness, equality of opportunity in the marketplace and all the other adjectives that describe a decent place to work. This is akin to the exceptions granted religious employers regarding discrimination in the workplace.  Why would a truly righteous Catholic/Christian employer even seek these exceptions/exemptions?  Humane rules are for the other guy who isn't a "religious" employer? 

Is this going to be the basis for the rallying cry of a new fortnight movement?  "Fortnight for keeping all advantages to the religious employer?"
