A new part-time employee shall attain seniority when he/she has
worked seventy (70) days within a six (6) consecutive month peri-
od. Prior to attaining seniority, as defined in this Section, the
employee shall be considered a probationary employee and may be
discharged without such discharge being subject to the grievance
procedure. However, the Employer shall not discharge or otherwise
discipline a probationary employee for purposes of evading the
terms of this provision or to discriminate against Union members.
Upon completion of the probationary period, the employee shall be
given a seniority date as of his/her first day worked within such six
(6) month period.
