"Good people don't cross picket lines." The TAs undertake the teaching of ethics on Day 2 of the strike.
I know it looks like the TAs are reading while picketing (which seems rather scholarly), but they are singing a traditional union song, and I believe those are songbooks, containing songs like these. I walked over the Park Street Bridge, the path from Bascom Hill to Library Mall, which takes you over the street and up to the second level of the Humanities Building. Two picketers were at the Humanities Building side of the bridge and this larger group of picketers was down at the end of the main stairway to the Building. I took a side stairway to avoid crossing the line. As I write this, I'm sitting in a café on State Street, and a large group of strikers marches up the middle of the street, toward the Capitol Building. (Their issue here is really with the state legislators.)
I wrote early today of the anti-strike chalkings. Here you can see that the TAs are correcting student writing, despite the strike, as it relates to the strike:
UPDATE: Here's a shot of the strikers as seen from the café:
