As aircrew will never stick together, on anything, it will continue. If crews stood up and said no, the stupidity would cease over night.
How right you are! I was employed in the Railway industry for three years. If you had told the Signallers or the Train Drivers that they could not bring more the x fluid ounces of liquid to work with them or have there yogurts/smoothies confiscated off them at security, then I am sure the RMT would have called an immediate strike. The network would have ground to a halt and it would all have been sorted out within 24 hours!
This topic has been well discussed on other threads but trouble is the politicians who agree to these crazy ideas are not subject to these draconian rules on a daily basis the way aircrew are.
