I think they should hear about the way Peel and the airport managment are treating ATC. The only problem is is that it would be bad publicity for the airport and so do no help to the current ATC staff as they are part of the airport, they would suffer as well.
I have heard that the member of staff BeaconInbound refers to was willing to return to work when the situation allowed and had to this effect already once during his wifes illness. The airport turned this offer down, which seems very stupid as the member of staff concerned was also an OJTI, verifier and an assessor and was such an invaluable member of the unit in that his abilities could be used to help train up new recruits and so help with the shortages in the staffing levels.
