From what i understand the jmc deal didn't offer much apart from a possibly insulting 3.5%. Even though the Britannia boys and girls received 3.2% they were given day off insurances and day off premiums worth up to £425. In jmc I belive only £50 is available for a day off.
The pension is set up for office staff as if you join with an ATPL (earliest age for attainment is 21) after full service to retirement at 60 you would still have to pay additional contributions to have you max 2/3 pensionable salary.
Even though jmc is part of the Thomas Cook group it is still possible to get cheaper TC holidays at you local high street.
This is just the tip of the iceberg. There are more gripes!
