Companies have benefited from employing refugees but will not speak openly about it for fear of adverse publicity, according to a report published on Tuesday.

Of the 10 companies surveyed for the Employability Forum, most had employed refugees because of labour shortages and a commitment to promote a diverse workforce, although only a few specifically targeted refugees.

Bosses highlighted the commitment, strong work ethic and high productivity that refugees brought to their jobs.

However, five of those questioned did not want their cases highlighted amid concerns of negative publicity.

Such concerns were creating a "significant barrier" to employers recruiting refugees, said the report.

"We need a serious debate about the realities of the British economy and the labour market, which in significant sectors depends on workers from abroad, without fear of companies and individuals being stigmatised for it," said Employability Forum director Patrick Wintour.

"The business community should not be intimidated by tabloid headlines."

TUC general secretary Brendan Barber called on the government, employers and other trade unions to actively work towards highlighting the benefits refugees bring to businesses.

"This is further evidence of the crucial but unsung role that migrant workers and refugees play in today's economy," he said of the report.

"Government, employers and unions must take on the increasingly unpleasant prejudices against migrant workers expressed by sections of the press.

"Instead we must make sure their contribution is recognised, that they are treated as full members of the workforce and enjoy the same rights and conditions as everyone else."
