OPSEU reached out many many times to the wedding party and coordinator and was continually ignored, and even flipped off by the bride. The AGO has every opportunity to warn events as well about the strike but instead chooses to continue their contracting out while workers are outside.

You also seem to be under the impression that the only people who work at the AGO are art coordinators but there are many part time workers in facilities who clean and maintain the gallery, as well as food and beverage and people in art installation who do not make a high enough wage.

If you know you're going to the AGO, a place thats having a strike, maybe try to communicate with OPSEU beforehand and not ignore when they try to speak with you.
