The agreement reached Thursday provides a 62 percent increase in wages for dockworkers and extends other terms of the current contract until Jan. 15. The International Longshoremen’s Association (ILA) initially demanded 77 percent wage hikes but has moderated its request. Numerous difficult sticking points could scuttle a deal before the new January deadline, but if the deal holds, the pay gains amount to a $24-an-hour bump in the top pay rate over six years.
