In Minnesota, you have a right to take time off of work to caucus. It’s guaranteed, if you give your employer ten days notice in writing. Today is caucus day, so that’s not an option for most, but you can still send someone to turn in a 2020 Precinct Caucus Non Attendee Form.
What’s going to be useful, now, is that if your form is accepted and your neighbors elect you as a delegate, you’ve got a right to take time off of work as a delegate or alternate to that convention!
