I'm surprised they weren't already in one. I worked at a competitor (the Wall St. Journal) years ago and all software engineers there had to be part of the union. Unions in the news industry are extremely common and powerful. My subjective experience with it was that union membership was mostly inconsequential for developers. The market for programmers is so strong that people would just leave if they weren't treated…
> all software engineers there had to be part of the union. Is that legal? Can unions or companies force you to join the union as a condition of employment?
If you weren’t forced to join then, in theory, management could subvert and then break the union by hiring lots of new employees who are compensated to “opt-out”.
