If you're serious about your DC pension you need 25% total going in, so whilst easy do give something for nothing on this, in practice the reality is that to have 25% going in will cost you 16% at easy, 12.5% at Monarch even if the offered level is not improved.
Yes you can pay zero and get 9% at easy - you will then retire on a pension of peanuts.
Monarch average annual hours over a career probably 600 if that, easy 850 so you'll work 30% less and might actually live to enjoy your retirement.
And by the way the pay ballot is no surprise to me.
And the gear's insured.
