DULUTH, MN. -- We're learning more tonight about the possibility of St. Louis County's Union plow drivers walking off the job. This after the Teamster's Local 320 members voted almost unanimously Sunday, authorizing a potential strike if their demands are not met.

What seems like an already long winter, could be getting longer. This strike could bring some uncertainty to the more than 3-thousand miles of road the county public works department is responsible for plowing.

As far as how those roads would get plowed if the strike were to happen, we reached out to the county for clarification, and they say St. Louis County will still be responsible for plowing and will release more details if warranted.

We did hear from a union spokesperson Erik Skoog. He says the about 180 union members are asking for changes to their wages, benefits, and health insurance.

Skoog said the strike authorization vote didn't have to do with recent long hours worked. He added that they will continue to plow during the rest of the negotiation process.

"Unfortunately after five rounds of negotiations and after two day of mediation, one which included a 19 hour mediation session, the teamsters chose to walk away. We're in a position where the county refuses to recognize a couple of issues that have been identified by the teamsters membership, as well as the union itself", said Skoog.

Skoog said the union has a strike date in mind.. but they don't plan on releasing it to the public. Their contract with the county expires December 31st.
