Service and trades jobs, largely unionized with hourly rates governed by contracts, can be found in grades 001-043. Administrative jobs can be found in grades 047 to 064. In the lower grades of this range, jobs tend to clerical and technical positions that are over-time eligible, hourly, and unionized. In the higher grades of this range (grades 056 and above), jobs are individual contributor, supervisory, managerial, or executive positions that are salaried (also called “exempt” from over-time).
