Union chief Mark Serwotka: Pension changes are 'unfair'
Hundreds of thousands of public sector workers are taking part in a 24-hour UK-wide strike in a dispute with the government over pension changes.
The government says current pension schemes are unaffordable because people are living longer.
But the unions say members are being "robbed" and will have to pay more and work longer for lower pensions.
General Secretary of the Public and Commercial Services Union, Mark Serwotka, says the unions are winning the argument over pensions and the changes being proposed are ''unfair''.
