Facts of the case: Rano was employed by Goodtime Food Products Ltd. for 7 years with no prior incidents. Rano worked at a packing station, primarily monitoring a machine that filled pickle bottles. She was occasionally moved to inspect bottles when there was not enough work. On the day of the incident, Rano was instructed by her supervisor, Ed Thomas, to report to the inspection area instead of her regular job. This instruction was communicated through another employee, Lucy Battaglia, who spoke Rano's language. Upon learning about her transfer, Rano became enraged, swore at Thomas, and made inappropriate gestures towards him with scissors, implying he was not listening. Rano, along with the shop steward, filed a grievance regarding her pay rate, as the inspection job paid less than her regular job. Thomas crumpled the grievance and discarded it in front of them. When Thomas later suggested that Rano use a local food bank to cope with her pay cut, Rano became further enraged, swore at him, and made threatening gestures with a knife, which was within three feet of Thomas. Following the incident, Rano was discharged by the company on the same day. The union filed a grievance challenging Rano's dismissal, claiming she was "disciplined without just cause," and requested her reinstatement with no loss of compensation or seniority. The dispute has progressed through the grievance process and is now set to go to arbitration. question: what are the key issues at stake in this dispute.
