Twin Cities janitors and security guards took a move toward a possible strike.
Saturday, Service Employees International Union Members voted to authorize a strike more than a month after their contract expired.
Workers say their wages have not kept up with the cost of living and it's time for a change.
If a strike were to take place, some 6,000 people would walk off the job.
