Dock workers load boxes of fruit at the port in Valparaiso city, about 121 km (75 miles) northwest of Santiago, January 8, 2014. Workers at the northern port of Angamos went on strike more than two weeks ago to demand that temporary workers be included in collective bargaining. The union says these workers are among the most vulnerable and need stronger protection. Other port workers then walked off the job in solidarity. The government deemed the labor action illegal and called for a swift solution to the stoppages. Around 110 workers at Angamos returned to work on Wednesday morning and operations at the port should return to normal in the next few days, port operator Ultraport said in a statement.
