To be fair, we have a very good relationship with the crews (barring a few bad apples, but you'll get that anywhere)
I think it helps for the crew to know who they're dealing with and to realise the job that we're trying to do. We recently moved next to where the crew have their re-currents, SOP's and initial courses and, as they say, respect comes from respect.
The improvement has been immense from both sides.
Even the boys up the front, as well !
