Michigan road workers are on strike due to contract negotiation issues. The unionized workers went on strike last week due to poor treatment and 14 months of negotiations that have failed to produce a new contract. Due to the strike, many road improvement projects have been delayed. The union has expressed that its members intend to strike until a fair contract is reached.
