The University of Illinois' board of trustees has unexpectedly called a closed-door meeting Monday to discuss employment and personnel matters.

University spokesman Tom Hardy on Sunday night wouldn't specify what the meeting will cover.

But it comes just more than a week after 130 faculty members called on university President Michael Hogan to resign.

The board decided Sunday to call the meeting, which will be in Chicago.

The faculty members criticized Hogan's management style and ethics after an outside investigation found that his chief of staff, Lisa Troyer, likely wrote anonymous emails intended to encourage faculty to support a Hogan-backed enrollment initiative. She resigned but denied writing the emails.

Trustees Chairman Christopher Kennedy last week said he supports Hogan.

Trustees have a regularly scheduled quarterly meeting on March 15.
