A spokesman from American Express UK said: "Following a period of consultation with employee representatives and employees, we have taken the decision to temporarily suspend company contributions to UK pension plans. This took effect from 1 July 2009 and the suspension of contributions will be lifted no later than 1 January 2011.
"We will continue to keep employees informed regarding whether we will be able to lift the suspension before this date."
