Just to add to the excellent Count’s post, in some of the contracts there is a guaranteed block of leave in Summer (from mid June to mid September).
There is not such a thing as an easyJet unique contract, every country has its own set of rules, in terms of money, holiday, pension, ftl limitations, part time options and rosters. It’s almost like working for different companies, that’s why it’s not easy to answer to some of the questions here.
