This gets tricky because there are Unions[0] and works councils in the EU, and they're different. Works councils[1] are usually per company, while unions are not. Neither maps precisely onto the conventional American definition of a "Union"[*], nor onto the AWU, which is a members-only union. I'm not sure how many Google employees in europe are Unionized, but I know works councils exist in multiple nations. [*]: My understanding is that a works council is government mandated, and a small group of employees can set one up, they have some formal negotiating power like a NLRA union, but don't represent all employees, and have a limited set of things they can negotiate about (for example they can deal with work conditions, but I don't think they can negotiate pay or strike). EU trade unions are big national organizations, one per industry that do lobbying and counter corporations. Conventional US NLRB unions have a monopoly on negotiations with the company, but require 50%+ membership. Members only unions have no formal legal power beyond non-retaliation, but can still negotiate with a company (about anything).
