They will be on the roof for 12 hours in an effort to reach the organization's campaign goal of $1.85 million.
Last year, through support of the community, the United Way was able to make a push toward the goal with the event.
All local radio, TV stations, outdoor media, businesses, restaurants and print media joined to weather the elements. This year, the organization hopes United Day for United Way is even better.
The event will begin at 7 a.m., and conclude at 7 p.m., Friday, Jan. 20.
The goal is to raise $25,000.
Business partners throughout the Wabash Valley will assist United Way in a one-day media blitz asking people in the Wabash Valley to contribute at one of many donation collection locations during the day.
Donation locations in Clay County include Fifth Third Bank, First Financial Bank, Terre Haute Savings Bank, Walmart, Harris Bank and Walgreens.
In addition, several restaurants will take part in "Dine United," where a portion of the sales from patron's meals at local restaurants will be donated to United Way.
The restaurants include Beef O'Brady's, Bob Evans, Boo's Crossroads Café, Buffalo Wild Wings, Carosi's, Clabber Girl, Dawgleg at Idle Creek, Gerhardt's, Patrick's Restaurant, Rick's Smokehouse and Grill, Roly Poly, Spaghetti and Sub House, Stell's Café and Tea Room with a Twist, and Wabash Valley Pizza Huts.
Local celebrities will also be pumping gas and washing car windows at Baesler's during the event.
Gas will be discounted and all donations will benefit United Way.
Local celebrities will also bag groceries at the store and take the groceries to vehicles.
