If 7500 is not already in a management position then he is well on the way. From the year dot I have not worked at a unit where there was not always a last minute scrabbling around for new staff when somebody in management woke up to the fact that Joe Bloggs was retiring at the end of the month or somebody had gone long term sick. Nobody seems to have worked out that even if you manage to hire an experienced controller it's going to be at LEAST 6 months before they are going to fill the position. I don't why I am surprised, the whole country is run by a complete bunch of amateurs
