An AFL-CIO committee is scheduled today to hear from a Roman Catholic priest and the head of Planned Parenthood as it struggles to come up with organized labor's first official position on abortion in time for the November elections.

The 18-member committee's recommendation -- expected to be adopted by the federation's executive council in August -- is likely to have little impact on this year's elections since labor has basically completed all its endorsements for November. The majority are candidates who favor abortion rights, with the notable exception of Gov. Robert P. Casey (D) of Pennsylvania, a staunch anti-abortionist, who is running for reelection against a Republican abortion rights advocate.

Several key leaders within the AFL-CIO fear that taking any position on abortion is likely to result in a bitter split within labor's rank and file. They also are concerned that if labor adopts a position in support of abortion rights, antiabortion groups will work to get union members to withhold a portion of their dues payments in protest.

The U.S. Supreme Court ruled last year that union members could withhold that portion of their union dues used for other than collective bargaining purposes if they disagreed with the policies of their union.

Supporters of abortion rights counter that taking their position will help labor attract more women to its ranks at a time when women and minorities are expected to account for more than 80 percent of all new job entrants during the balance of the century.

At its first meeting in April the committee decided to hear from one person on each side of the abortion issue, picking George Higgins, a Roman Catholic priest with strong ties to labor leadership, to speak for the antiabortion forces and Faye Wattleton, president of Planned Parenthood, to represent abortion rights supporters.

Writing for Catholic News Service earlier this year, Higgins warned that labor "will suffer dire consequences" if it adopts a pro-abortion-rights policy and will risk "alienating a large segement of its membership at a time when the {labor} movement is on the defensive."
