Janitors who have been striking against unfair labor practices in Houston, Texas, say they are taking their struggle nationwide with picket lines in eight cities across the country. Janitorial workers in Los Angeles and Denver are expected to show solidarity by refusing to cross the picket lines against cleaning contractors. The strike in Houston is now in its second week after workers making $8.35 an hour say they faced harassment and intimidation when they rejected an offer that would have raised their pay by just 50 cents an hour over five years.
