A lady phoned in to say that she applied to an engineering firm and "because she was a girl" (and they'd never hired one before!), they put her on a rate of pay £1000 pounds less because they didn't know whether she'd be any good! After six weeks, she'd proved her worth and her wage was raised to the standard rate.
This was decided not to be discrimination in their discussion 
Another caller said she was earning less than her three male counterparts but apparently there was no reason to say she was being discriminated against because the other three were sagittariuses(sp.?)?!
