Why did unemployed university graduates form collective associations in some countries in the Middle East and North Africa but not in others? Despite similar levels of grievances around educated unemployment, reversals in guaranteed employment schemes, and similarly restrictive conditions for mobilization, unemployed graduates' associations formed in Morocco and Tunisia but not in Egypt. Conventional explanations - focused on grievances, political opportunities, or pre-existing organizational structures - cannot account for this variation. Instead, I point to the power of ideologically conducive frames for mobilization around the time that grievances become salient. A strong Leftist oriented tradition of student unionism in Morocco and Tunisia was necessary for the emergence of a rights-based discourse around the "right to work." This was not the case in Egypt, where Islamists, not Communists, dominated student politics at the time that grievances around educated unemployment became salient. This article offers one of the first comparative studies of the mobilization of the unemployed in a non-Western, non-democratic context.
