I think most NATS 'day' staff are contracted for 37.5 hours a week. Which is 9-5 Mon to Fri with a half hour for lunch.
actually, the Employee Handbook Part 1A Chapter 3 says
Normal hours of work for full-time employees are 40 gross hours (i.e. including meal breaks) for a 5 day week.
And the only reference I could find to meal breaks was to one break of no more than 1 hour.
