List of Radio Strikes

This began with a post here. The below image  got me thinking. These days the only strike that shuts down a radio station is a lightning strike. So I began to research strikes at radio stations. There is no canonical source of this data so I have been updating this list as I discover pertinent events in other research. It will be ongoing.
Strikes are traditionally the tool of people that perform manual labor, blue collar workers. In general, white collar workers don't strike. It's a generalization, but it's fairly accurate. This list is a list of exceptions in a way. It's limited to white collar staff: writers, producers, announcers, musicians etc. I have excluded the strikes of TV staff, radio manufacturers, and telegraph operators as those are not strictly broadcasting-related. This is an incomplete list, but I have hopes that readers may make a few additions.
