(Reuters) - Google employees from across the globe are forming a union alliance, weeks after more than 200 workers at the search engine giant and other units of parent company Alphabet Inc formed a labor union for U.S. and Canadian offices. Alpha Global was formed in coordination with UNI Global Union, a union federation that represents about 20 million workers globally, and includes unions from countries such as the United States, Germany, Switzerland, Sweden, and the UK, UNI Global Union said.

Alphabet was not immediately available to comment.
