It is sometimes spelled pro-rata, but this is technically a misspelling of the Latin phrase. In North American English this term has been vernacularized to prorated.
My definition: Pro rata, when it comes to jobs, generally refers to pay. Say the salary is '$40,000 per annum-pro rata', it will mean that if you only work part time, you get part of the pay. A standard week is (about) 40 hours, so the pay for 20 hours will be $20,000 per annum.ay the salary is '$40,000 per annum-pro rata', it will mean that if you only work part time, you get part of the pay.
