Leave
From personal experience.
Leave is applied for on the intranet, if the dates appears in the right color you would think that the leave will be ok.
It remains unconfirmed until the issue of the roster containing your leave dates which makes booking anything a gamble.
If your leave dates straddle two rosters: ie you have booked two weeks but only have one confirmed, there is no avenue available to find out if you will be required for duty at the end of you first weeks leave until you leave the beach, log onto the intranet and look at your new roster.
Leave is indeed tagged onto ones days off without consultation: so your annual leave is now at Cityjet's complete convenience.
Colleagues have been given leave, booked holidays, and had the leave withdrawn by email some weeks later.
Tax regime: The French revenue are understandably upset that french Nationals, living and working in France pay their taxes to the Irish government.
Does the company for one moment believe that the UK Inland revenue will take a different view given that crew members do not comply with the 90 day rule ?
A base is a base, and within the EU that is not negotiable !
