SHICKSHINNY — Teachers are on strike today in Luzerne County's Northwest Area School District.

District negotiating committee member Daryl Morgan said talks Monday went well but differences remain over wages.

Teachers have been working without a contract since August 2005, and they point to a wage freeze in the last two years of their previous contract.

District officials point to increasing costs of health insurance for the teachers, who so far do not pay a share of their premiums.
