The City Council voted to close City Hall on Fridays and extend its hours Monday through Thursday for a six-month trial beginning Nov. 30.
City Hall will be open from 7 a.m. to 6 p.m. for the four-day workweek. The changes were made at the request of the Teamsters Union, which represents many of the city's employees.
Phone calls, however, will be accepted only between 8 a.m. and noon and 1 and 5 p.m.
City Clerk Kathleen Midstokke said she opposed the change because it will restrict people's access to public records and because most inquiries are made by telephone.
A city survey of 416 people who use City Hall services showed that 70% of the respondents favored the four-day-a-week schedule, which includes having city offices opened during the noon hour.
