The union was protesting at the removal of 37 teachers from nursery schools in the city. In the argot beloved of aged lefties, they have now been immortalised as "the Glasgow 37". They were so christened in a statement put out last week by the scourge of the EIS establishment, Peter Quigley, who upset the apple-cart by getting himself elected as the institute's vice-president.
Not since the heady days of the 1970s and 80s have we seen such solidarity.
Our more seasoned readers will remember some of the cause cel bres who kicked against the pricks at that time - the magnificent "Kirkland Five" from Fife and the outstanding "Bathgate Twelve".
Right on, man.
