The TUC hopes that the worksmart.org.uk site, which launches today (29 August), will boost interest in union membership among Internet-enabled employees in new economy jobs. Employees in the sector have so far shown little inclination to sign up to a union.
Last year, both the Communication Workers Union and the Graphical, Paper and Media Union attempted to reach out to new media employees, without achieving significant results.
John Monks, TUC general secretary, said, "This is a major new initiative by the TUC to reach out to Britain's new Web-enabled, but often non-union, workplaces.
"The best way to show the continuing relevance of unions to every workplace is by providing practical help and a taste of what unions do," he said.
Topics covered on the site include holiday and redundancy rights and advice on handling stress, repetitive strain injury and back pain.
New channels that will be added to the Web site over the coming months will include advice on pensions and other financial matters, and information about job hunting and career development.
Monks said the Web site was designed to help all employees and was more than just an attempt to boost union membership. "There is no hard sell or hidden catches," he said, "but our union-finder provides an online gateway to union membership. Worksmart is there to help today's working people get the most out of the world of work."
