I'm also unsympathetic, but I mean to keep that separate from this puzzle.
Some Arts undergraduates are "striking" tomorrow to demand the abolition of tuition.
They are also mass-emailing professors asking the professors to cancel classes in support of the strike.
But if the professors cancel classes, in what way are the students on strike? The professors are then on strike for a day. Students-- if we continue to use the labor law language that doesn't really make sense in this context anyways-- are then being subjected to a lockout. But their refusal to show up becomes irrelevant, because there's nothing to show up to.
Conceptually, wouldn't faculty compliance with this request abolish the student strike and just turn it into a faculty strike?
