I have nothing but the greatest respect for Ops and Crewing Boys and Gals. They tend to get all the crap from Handling agents, crews, their boss,etc., and generally still produce the goods.
At Go, all newly promoted Captains spend a day in OPs/Crewing, and a day on the ramp with the Go Team Supervisors, as part of their Command Course. It gives them an insight into the workload when things are going seriously pear-shaped, and reduces the level of nuisance RT/Phone calls.
Cheers
