The votes are in and the results overwhelmingly support Iowa teachers keeping their union affiliations. Members of over a dozen teacher bargaining groups voted over the last two weeks to maintain their affiliations under the state's new collective bargaining rules. Says this week's final tally showed more than 1,100 of the 1,300 eligible voters cast ballots affirming their union affiliations. Under the collective bargaining laws, public-sector unions must re-certify every time they face a new contract negotiation, which could be every two or three years.
