weeks ended on and between January 9, 1975, and April 3, 1975.  They refute rather than support Florsheim's contention.  Four of the pages are for the South Hills Village store; they show that on January 9th there were three part-time employees and that the Florsheim National General Manager directed the elimination of one part-time employee.  That was done.  On January 30th, when there were two part-time employees, he directed the elimination of one, but that was not done.  On February 13th he directed the elimination of both part-time employees, and one was eliminated.  On March 13th one part-time employee remained on the payroll and the directive was, simply to "reduce."  Two pages record the payroll data for the Northway Center storewhere on January 30th there were three part-time employees.  The elimination of one was directed.  On February 13th, however, the number of part-time employees had apparently increased to four, and the elimination of two was directed.  The Monroeville store on February 13th had two part-time employees and the directive was simple to "reduce" part-time.  On February 13th the Smithfield Street store in Pittsburgh had two part-time employees, and the directive was to reduce part-time help.  On April 3rd there were three part-time employees at the Fifth Avenue store in Pittsburgh; the directive was to reduce part-time "Hours."
