FM you're not naive (at least I don't think so
) I think it is the sign of the times! There are just very few jobs out there at the moment.
I remember back in the early 90's, friends leaving university thinking they would walk straight into a job but were caught up in the resession that was going on at the time. They did all eventually get jobs but not necessarily in the fields they expected to.
My DH (then boyfriend) and I gave up our good jobs in 1990 to go travelling. I was very lucky to get my job back after a year (with a pay rise!) but the OH wasn't so lucky, he had been a draughtsman and the building trade was badly effected so he went for a complete change and joined the police force!
Good luck to your DD - something will come along eventually.
