A whole range of workers seem to be walking out of their jobs in solidarity with the protesters. We've already mentioned Cairo University staff and journalists but Ahram online reports that over 6,000 Suez Canal Company workers from the cities of Suez, Port Said, and Ismailia began an open-ended sit in today over poor wages and working conditions . And thousands of Telecom Egypt staff at various branches are protesting and threatening a sit-in if their demands are not met.

The reach of this movment continues to expand.
