Most of the management team at the Illinois State Museum has retired or taken other jobs amid the museum's closure due to a lack of a state budget.
Gov. Bruce Rauner's administration closed the museum to the public on Oct. 1.
The (Springfield) State Journal-Register reports that the administration has laid off about a dozen members of the museum's management team.
Museum board chairman Guerry Suggs says only three or four members of the management team would be available to return should the museum reopen.
Union employees working for the museum have spent their time doing curation work and other duties since the museum was closed.
A bill designed to keep the museum open has been sent to the governor. Rauner spokeswoman Catherine Kelly says the bill is under review.
