Richard Prince, general manager of Swissport Stansted said: "The proposed changes to working patterns will achieve a proportion of the necessary savings we need to make to offset our decline in revenue and it means we will avoid job losses.
"We are not cutting people's pay. We are not increasing the amount of hours they work. We are asking people to spread their contractual hours over a five-day week and not a four-day week. We are keeping people in jobs."
