This is urgent - please act and pass this message on to friends, co-workers and colleagues.

Mehedi Hasan, a field investigator for the U.S.-based Workers Rights Consortium, was jailed seven days ago in Bangladesh as part of crackdown on trade unions.

His family is not allowed to see him, and workers' rights activists have expressed fears for his safety.

Please help us to mobilize thousands of people around the globe in a massive email campaign and flood the Bangladeshi government with messages calling for his immediate release -- and for an end to repression of trade unionists in that country.

And please -- pass this message on.
