The Port of Boston was closed yesterday as the largest longshoreman's strike in decades began along the Atlantic and Gulf coasts. 

Around 300 unionized workers at the Port of Boston walked off the job as the strike began. 

Massachusetts businesses are concerned that the shutdown of ports could lead to shortages of products and higher prices. 

Conley Container Terminal in Boston handled around 145 thousand shipping containers in the fiscal year that ended June 30th.
