Raleigh County House of Delegate Ron Thompson hasn't attended any legislative sessions since May.
Legislature staff members have been unable to reach him by phone.
House Speaker Rick Thompson has given the Raleigh County delegate until January 25 to take the oath of office, or he may have to forfeit his seat.
That's when the House Rules Committee would meet to determine Ron Thompson's fate.
He is one of 5 Delegates from the 27th District, which serves Raleigh and Summers Counties.
