I can't speak for all the downvotes, but I just don't understand what the comment had to do with the article it's supposedly commenting on. The article describes Google's weekly meeting where executives answer adversarial questions from employees, in which employees expressed that they're concerned about future layoffs. What part of that story would be different if more of them had joined the union? If the implication is that unionized employees never have to worry about layoffs, that's not accurate.
