My arse, they do.
We recently sent out four invitations to interview for a nursery assistant's job at our nursery. Three canditates were 'native English' and the fourth was Polish.
Of the three 'English' -
-
Didn't turn up.
-
Didn't turn up, and when we phoned to find out where she was, were told she'd moved to Bradford.
-
Turned up and when asked to email a CV (after informing her that the Job Centre would help her with this, if necessary), didn't.
-
Polish girl, turned up 10 minutes early, pristine and with CRB check, references etc.
Guess who got the job?
