I'm a Senior First Officer with EJ.
I have methodically gone through the figures.
1) Based on 600 sectors a year my net take home pay will not change. (Don't forget to subtract National Insurance in the calculations!).
2) The pension, as it stands, will see many people in "shock" when retirement beckons, their first monthly pension cheque falls through the letterbox and is compared with their very last pay cheque. Just ensure a) mortgage is repaid, b) kids are educated, c) kids are earning and in their own gaffs, d) you've had enough foreign holidays, e) your buddies are happy that you won't be joining them for the weekly beers, f) your vegetable plot is well fertilised, g) you know where to buy cheap.
3) Based on the current 5254 arrangement all of the above is probably irrelevant as you won't live to see it.
4) Minimum annual leave should be increased to 30 days - it's standard in most other industries.
