(i.e. not a new intake of fresh cadets on the 6-month probation £1k/month contract.).

Are you serious 1k a month ? I realise these guys and gals are straight out of flight school but 1k a month to fly an Airbus for a major U.K airline is an absolute disgrace, even as a six month "probationary wage". Ten years ago I used to get paid 1.2K a month working five days part time in Tesco. No wonder Easy jet are hoovering up as many CTC graduates as possible its costing them absolute peanuts.
I don't mean to sound like im having a go, I know everyone is just trying to catch a break and I think it is great that there a chance to go into an airline straight out of training but this has got to stop, where on earth is people's self respect? Where are we going to be ten years on with this going on? I could maybe justify it if there was a permanent contract at the end, pending satisfactory performance of course but this is just pure taking advantage.
I think any company worth working for recognises the value of it employees and doesn't mess around, either you employ people on a permanent contract and pay them a proper salary commensurate with their qualifications or you do whats going on here and you just create bad feeling and de-motivation and how on earth the guys that have been with the company a long time feel about this I don't know but shame on you for allowing this to even be thought about by the company, it should have been put to bed and never seen again the moment it was mentioned by management.
I guess thats the world today it's "im alright jack" nobody gives a toss about anybody else as long as they still get their slice of the pie.
Just my two cents......
