I wouldn't expect to have professional development overtly included in a short term contract, either. I'd expect a much higher hourly rate to pay for it though,

I wouldn't expect to have professional development overtly included in a short term contract, either. I'd expect a much higher hourly rate to pay for it though, amongst other things.
