I must confess I'm not an expert on Jordanian labour law, but in Jordan, as with so many other countries, there's an enormous gap between the statutory protections and the enforcement of those protections. I think that often with respect to matters of discrimination, and particularly with respect to matters involving migrant workers, the enforcement of Jordanian law is flawed.
I have no evidence to suggest that the recent reforms to which you refer—for example, the 2010 reform regarding workers organizing and migrant workers organizing—have led to an enormous increase in the organization of unions in Jordan.
