The United Steelworkers of America last week opened what U.S. Steel Corp. Chairman Roger M. Blough called "our guaranteed annual argument." The 1,250,000-member union, whose two-year contracts with the industry start expiring June 30, will submit a list of 22 demands when new contract negotiations start next week in Pittsburgh's William Penn Hotel. Among the proposals:
¶ Premium pay for Saturday and Sunday by some 30% of the industry's work force (average wage: $2.45 an hour).
¶ Supplementary unemployment benefits, similar to the United Auto Workers' Guaranteed Annual Wage, to compensate laid-off workers for as long as 52 weeks.
