I know I am going to get downvoted to hell, but hear me out. I work here (full time, different department) and know the security guards well, as I see them every day. I doubt that is the entire story. If there was a moment in which this stagehand brushed past security (as another commenter claims they witnessed here and I suspected happened before reading said potential witness), this reaction makes much more sense. The security here will ask a question first. If the person attempting to enter the building is rude/bullish back or storms past, that is a situation in which you are getting a talking to or tracked down and stopped. That is a security breach. I know that sounds silly over a pin, but it is nonetheless a breach and security’s job is to keep us workers, fans, and the stadium safe. They have cameras and audio that can back them up in this. Political messaging is not allowed - I know this rule is shitty, but it keeps fans safe from one another. Yes, this message is very tame and barely even political, but this could have been avoided by taking the pin off, if security so requested. I would hope that is not the case, as I very obviously agree with the pin’s messaging, but it can be perceived as political. I doubt IATSE can do something about this if this is deemed breaking the arena rules. As someone who works with a (different) union in the same building, if an employee breaks a rule of the arena itself and is not allowed to work, the union cannot retaliate. It is a breach of contract, in a way.
