Off-spring tells me that the Union has not agreed with 'dress code' yet, to be discussed at next shop stewards meeting!
Strange, because there is a letter from Prospect, on the TC Ops door stating that NATS are entitled to run the Ops dept etc the way they wish, if it is reasonable, and that the Union did not feel they needed to get involved in this instance... they do not oppose what management have said and are aware.
