You'd condone that would you?
Yes, I would. As you rightly point out, if the strike goes ahead (which hopefully it won't and an agreement will be reached through Acas on Tuesday) there will undoubtedly be disruption. As a passenger who is due to travel on the day of the first strike, I'd like to know that the start to my trip is going to be safe and that it is not going to be ruined by an unwelcome, and completely avoidable, extended-stay in the departure lounge.
I don't mind being delayed to a certain extent and I agree that working conditions for some at the airport are very poor, but I would rather the airport brought in trained staff from CPH to deal with important issues such as security rather than hastily trained "receptionists and phone operators" as you put it.
