You've got to be kidding me

"The internship programme is free for qualified candidates. The position is not salaried."
I beg your pardon? You want fully qualified vets to spend a year working for you, often more than 12 hours a day, in addition to nights and weekends, while working on their dissertation at the same time. And you won't pay anything?
Look, I don't expect to earn enough money to pay for a place to live *and* food. But, you know, every other hospital I've seen so far offers at least something. Interns in Edinburgh lived in a small flat at the clinic for the year (actually, I think they even got paid). The hospital for internal medicine at your uni pays at least a small amount. Probably more symbolic than helpful.
But nothing? You've got to be joking.

I refuse to earn less than a cashier for more work in addition to five years of vet school.
Acutally, I probably will work for less. But I won't work for nothing. (See me give in and work for free in five months)
