Officials representing Operation PUSH and Nike Inc. have agreed to meet at Georgetown University today in an attempt to resolve what has become an increasingly acrimonious standoff between the sportswear manufacturer and the Chicago-based civil rights group.

Nike President Richard K. Donahue and Chairman Philip H. Knight are scheduled to meet with PUSH President Tyrone Crider and founder Jesse L. Jackson at the behest of Georgetown basketball coach John Thompson, according to a source close to the talks. It will be the first direct contact the two sides have had since discussions about minority involvement in the company broke down July 31.

Until yesterday Nike officials insisted they would not meet again with PUSH unless the civil rights organization answered questions about its composition and finances. Earlier this week Nike officials turned Crider away from its Portland headquarters after they rejected his request for a meeting.

"They're like two banty roosters," said Richard Brown, the director of Portland's chapter of the Black United Front. "They've really dug in, and they're not giving in at all."

PUSH, which has launched successful boycotts against a half-dozen other corporations, has been urging consumers to stop buying Nike shoes or to cover the Nike emblem on the sportswear they already own.

Thompson, whose coaches' contract with Nike earns him about $200,000 a year, met with Jackson last week and indicated he would try to mediate the dispute. Jackson had criticized Thompson, Chicago Bulls basketball star Michael Jordan and other athletes under contract with Nike for defending the company.

Both sides have been rigid in their demands. Crider has said Nike must buy advertising in black-owned media outlets and add a black director to its board. Nike has countered by detailing the charitable contributions it makes to the minority community and announcing that it would recruit a minority director and vice president within two years. Company officials have argued that Nike was being singled out for criticism because PUSH had received a financial contribution from Nike's chief competitior, Reebok International.

PUSH's call for a boycott has met with mixed response even in the black community, the base of its activities. "They both want questions answered before they will do anything, and that's not getting us anywhere," said Brown.

PUSH officials say they have received nationwide support from Nation of Islam leader Louis Farrakhan, the National Council of Negro Women and the Southern Christian Leadership Conference. But representatives of the National Urban League and the National Association for the Advancement of Colored People said this week that they have not decided whether to endorse the PUSH action.

Meanwhile, Nike stock has dropped significantly since mid-July, from $91.875 to $59.75 yesterday. Industry analysts have hesitated to attribute the slide to the boycott because Wall Street's overall performance has suffered from a sell-off of over-the-counter stocks.

But the boycott doesn't help, they said. "Any time there is a controversy, Wall Street will react to it," said one analyst.

Tammy Blank, the shoe manager for Chicago's M.C. Mages Sports, said the eight-floor store has continued to sell 30 to 40 pairs of Nike shoes a day for $70 to $100 a pair.

"I don't think it's had any appreciable effect economically," said John Horan, publisher of the Sporting Goods Intelligence newsletter. "Just because Wall Street gets nervous about this stuff doesn't mean its happening out there {in retail sales}."

Nike, which has 3,000 employees and $1.7 billion in annual sales, announced a 24-month affirmative action plan last week and cited employment figures that show minorities make up more than 14 percent of its work force. In a letter to employees, Knight said that PUSH focuses narrowly on black employment while Nike counts all minorities as part of its affirmative action response.

Like other athletic footwear companies, Nike has targeted its advertising toward black inner city youth by featuring Jordan, San Antonio Spurs player David Robinson, baseball-football star Bo Jackson and filmmaker Spike Lee in its advertising.

Crider said yesterday that, if the dispute is not resolved at today's meeting, PUSH plans to expand its boycott by setting up informational pickets outside of stores that sell Nike products and traveling to major cities to drum up support.
