There's a very good article by Hesham Sallam, called Striking Back at Egyptian Workers in the new issue of Middle East Report. It details the hostile rhetoric and actions by the military, interim government, and many commentators against the wave of industrial action and strikes that have taken place since the revolution.
This part of Sallam's piece on the treatment of strikers post-revolution is spot on:
Shortly after the resignation of Husni Mubarak on February 11, Egypt witnessed the rise of what Egyptian authorities and media outlets began describing as ihtijajat fi’awiyya or small-group protests. The Arabic term fi’a simply means “group,” but has acquired negative connotations and might be compared with how the term “special interest” is used to disparage American labor.
