UK - Directors at the UK's top companies enjoy pensions worth up to 25 times more than most staff pensions, according to the Trades Union Congress (TUC).
And directors with the greatest entitlements had average pension pots of £5.2m and could therefore expect a pension of £333,400 a year.
The survey showed bosses had bucked the trend towards riskier and less generous pensions for ordinary workers, with three quarters of the directors surveyed on defined benefit (DB) schemes.
It found directors in defined contribution (DC) schemes received an average employer contribution of £91,700.
While many employers across the public and private sectors are increasing the length of time people have to work by raising retirement ages to 65, the majority of directors in the study were still able to retire at 60.
TUC general secretary Brendan Barber said: "As ordinary workers have their pensions schemes closed and are expected to work for longer, the UK's top bosses are avoiding this collective belt tightening and retaining their gold-plated pensions.
"Top bosses justify their lavish pay and pension arrangements on the risks they take and the rewards they deserve for success. But these credit crunch-busting retirement plans seem to exist in a different world from the economic squeeze that is affecting everyone else's pensions."
Barber explained many of the most lucrative pension arrangements were "shrouded in secrecy" making it harder for investors to scrutinise them and ensure that bosses were accountable.
He said: "If top directors can really justify their rewards they must be bolder in declaring their pay and pensions to investors and their staff."
Some of the UK's biggest pension schemes will be forced to report on climate risk in line with recommendations from the Taskforce for Climate-related Financial Disclosures (TCFD).
