 Twin Cities, I'm Phil Picardi for NPR News. Hundreds of Minneapolis park workers are on track to strike over the 4th of July.

The union says the latest offer misses the mark on sufficient wage increases and hazard protections. Park keeper Hunter Hoppe assembled picket signs. A lot of us have second jobs.
