SEIU 49 has recently added 800 new members to their roster after a vote by Providence Portland Medical Center. There was an issue with tallying the number of votes, however, after much scrutiny, it was determined that the final number of votes (384-383) favored unionization. Workers felt that executives were obtaining high salaries at the expense of workers, which sparked their need for union representation.
