As part of the Republicans' budget "plan", tomorrow is the first of five "furlough" days for state workers between now and the end of the year. "Furlough" is a euphemism for "unpaid day off."
Most state workers won't be in the office/at work tomorrow. The main exceptions are those in law enforcement, judicial, and public safety roles.
The complete lists of agency closures and statuses can be found here, on the website of the Arizona Department of Administration.
