In Washington State the legislature has had to be in special session since it did not produce a budget for the state in the regular session. The cost to taxpayers is presently recorded at $77K, but might be $100K when the numbers are finalized. This was for a 30-day special session; and it appears another special session will occur.
The cost is due to daily per diems of $90, claimed by most of the legislators. Some have taken the high road and not claimed per diems for the special session, stating that they don't feel they should since they didn't get their job done in the time allotted (the regular session). (Both an R and a D were noted in the article who have foregone their additional per diems.)
Other costs are also associated with having the special session.
And all this time and zero legislation passed; and no budget. Could the private sector sustain such lack of productive employees?
