Here's what the Contract says . . .
ARTICLE 18. SAFETY AND HEALTH EQUIPMENT, ACCIDENTS AND REPORTS
Section 6. Building Heat
Centers will be heated, where practical.
On a facility-by-facility basis, the Employer will evaluate whether additional ventilation or heat is needed for purposes of safety and health. This will include clerical work areas outside of office structures in the UPS facilities. Should clerical employees have concerns with respect to these two (2) issues, they shall be addressed by the appropriate local CHSP Committee. Should the local CHSP Committee not satisfactorily address the issue, a grievance may be filed and would be sent directly to the National Safety and Health Grievance Committee.
