Defined Benefit (e.g. civil service) v Defined Contribution (all new schemes).
By backing the Bank of Ireland unions I think FF are just playing politics. Banks are easy targets & gets the state out of its duty to provide state pensions.
I see no problem with moving new employees to defined contribution as defined benefit are too prone to under funding as company is solely responsible. Because people live so long now a defined benefit pension could have unimaginable outgoings for ever extra year someone lives after retirement. Companies still contribute to defined contribution schemes but more easy to estimate costs.
