Despite progress, hidden racism still pervades Britain's workplaces, according to a new report.

A TUC study published on Friday found that many of Britain's ethnic minority workers still feel that more needs to be done to create equality in employment.

Respondents to the survey expressed concerns ranging from the lack of black and ethnic minority figures at senior management level to problems over pursuing complaints about racism.

TUC chief Brendan Barber said that anti-racism measures in the work place had progressed and "brought real benefits to large numbers of workers".

"Now the government must legislate to force all employers to rid our workplaces of racism. Unions are ready to work in partnership with employers and the government to guarantee equality for all at work," he said.

The "Black voices" study found that although overt racism in the work place had been significantly reduced many workers felt that more could be done.

The report contains a number of recommendations, including proposals to improve training for senior managers on discrimination and improve complaints procedures for victims of abuse.

It is hoped that such measures will remove workplace pressures for ethnic workers to "blend in".
