A trade union report has found that only 6% of UK job adverts mention workplace pension packages, despite growing government pressure to help employees plan for retirement.

The annual survey, carried out by the Trades Union Congress (TUC), looked at 1,132 job adverts in national and local press and discovered that only 69 of them mentioned details of a company pension scheme.

The union warns that employers are missing out on opportunities to attract good staff by boasting about the availability of a pension, especially in the light of recent concerns about the effects of low birth rates, rising life expectancy, the 2000-2002 fall in stocks and low bond yields.

According to the Department for Work and Pensions (DWP), 10 million UK workers are not trying to save for retirement, partly because firms are not telling them about what pensions are available.

Over the past few years, many firms have reduced the amount of money paid into pensions, and have been closing their final salary schemes to new employees because they can be too expensive.

However, the TUC report argues that employers can actually benefit from advertising their pension packages in job adverts, claiming that prospective employees would be more likely to take the advertisement seriously.
