You will find that even if you come in on separate "single" contracts that each of them will state that if you are married and your spouse receives separate benefits from their employer that you cannot duplicate benefits (i.e. 2 accomodation allowances, 2 sets of tickets home, 2 whatever) you will have to use one or the other, not both.
And if you think you'll be able to fly under the radar, I've known couples who did so, ended up being caught, and having to repay substantial sums to one or the other employer. Not worth it.
