Email Humberside Airport to see what their work experience policy is. I doubt you'll be able to do something as specific as job shadowing ATC, but more than likely HUY will have a designated programme for work experience students, usually (if it's like EMA) working predominantly on the information desk as your base, but then being taken out to various departments to see what they do. Also try contacting Servisair at HUY. We take on work experience students all the time.
