Kenny, Kenny, Kenny (sigh).... Now just where did you get your figure of "only 15 controllers short next year"???
Let me guess. Mr Cheese 'n Ham?
Now, Kenny, we've been here before haven't we? Let's recap. Who was it that told you that NATS had 60 controllers too many last year? Aha! Has the penny dropped?
The FACTS. New validations are FAR outstripped by retirements. When controllers retire they take several validations with them (T+P, different sectors). Most of the "new" controllers are single sector only, some "T" only.
Overtime, and minor changes to WPP will help, BUT NOT GREATLY. They might just enable Swanwick to run at LAST SUMMERS levels, but no more.
It will take YEARS, before NATS has enough controllers. There is no quick fix. Be honest, with your customers and your staff. It would help.
