Should they be made to show ALL THEIR EXPENCES? & justify why? should they be allowed Subsidized meals? If they are sacked from their posts, should they be eligible for a position with the same salary?
I'm pretty sure access to MP expenses is available to all those who are interested.
Subsidised meals, I can't say I have much of an opinion but there are many others who benefit from the same dining facility who are on a lesser wage, discriminating between the two would cost more than the value of the subsidy in all probability.
It is entirely up the the employer who they employ and what salary they offer.
