Oh, this is because the page linked above is for the “Times Guild”, not the Time Tech Guild. Times Guild is the journalists; the Times Tech Guild is the product engineering folks that just authorized a strike. They are two separate unions within the Times. They support each other but do mot have precisely the same platforms or negotiations with the company.
This press release goes into more detail as to the motivations for the strike: https://www.nyguild.org/post/new-york-times-tech-guild-votes...
