Background

Supervising post office operations requires supervisors to possess the knowledge, skills and abilities to manage delivery (city and rural), retail, and customer service operations requirements as well as frequent interaction with the public.

The U.S. Postal Service uses the Supervisor Workload Credit (SWC) worksheet to determine the number of Executive & Administrative Schedule Customer Service Supervisors in post office operations. SWC worksheets are completed on a facility by facility basis, to calculate the span of control – the number of employees that report to each supervisor. Post Office Operations does not have a span of control target. However, a Postal Service Management Structure Study dated July 2003 determined the average span of control of 1:26 for postmasters was consistent with accepted best practice trends.

In fiscal year (FY) 2016, the Southern Area had 2,255 supervisors in post office operations, with 69,341 employees reporting to these supervisors, for an average span of control of 1:31 (one supervisor per 31 employees). The Southern Area had the highest number of supervisor vacancies and supervisors used 5,765,642 workhours and 805,108 overtime hours.

Our objective was to assess the span of control and use of supervisor workhours in post office operations in the Southern Area.

What the OIG Found

Our analysis of the 12 Southern Area districts showed the average span of control ratios ranged from a low of 1:27 to a high of 1:33, slightly higher than the accepted best practice average of 1:26. In addition, the span of control at 25 of the 34 individual post offices we reviewed exceeded best practices, ranging from 1:27 to 1:73. We found the high span of control at some units in the Southern Area impacted supervisors’ workhours and their ability to effectively manage daily operational tasks.

Supervisory span of control challenges occurred in Southern Area facilities due to 292 vacant supervisor positions, and supervisors frequently detailed to higher level assignments or to other vacant supervisor positions. Span of control challenges along with the supervisor’s daily workload also contributed to their ability to effectively manage daily duties and responsibilities at some units.

Consequently, supervisory workhours exceeded the area’s FY 2016 plan by 303,670 hours and also contributed to the use of 805,108 hours of overtime by supervisors throughout the Southern Area. Additionally, facilities with the 292 vacancies accounted for 125,358 workhours over the plan and 238,743 hours of overtime. Filling vacancies and managing personnel assignments would improve the span of control ratio average and the supervisor’s ability to effectively manage daily operational tasks and reduce supervisor workhours.

Southern Area management stated they had several strategies in place to address supervisor vacancies. In May 2017 area management implemented additional strategies to assist districts that included assigning every district an area human resource analyst and conducting weekly meetings with all district human resource managers to discuss each vacancy and actions taken to fill these vacancies. Therefore, we will not make a recommendation on this issue.

In other matters, we identified the SWC worksheet used to determine the authorized number of supervisors in post office operations does not give consideration to all of the supervisors’ daily administrative responsibilities. The SWC’s primary measurement is the number and type of employees supervised and does not include factors for supervisors’ duties and responsibilities when managing these employees.

On March 18, 2017, the National Association of Postal Supervisors in conjunction with the Postal Service initiated a SWC work study at 34 pilot sites in six districts in the Northeast Area. The work study will include a review of supervisors’ daily duties and responsibilities. Therefore, we will not make a recommendation on this issue.

What the OIG Recommended

We recommend management monitor the use of supervisors to detail assignments to lessen the impact to post office operations.

    It's ridiculous that a supervisor works as hard as they do and make far less than the carriers they supervise! And then be put in a OIC management spot and then has to work a day off for free and then work for free on Sunday and holiday amazon ... and his pay is less than a CCA makes now! It's appalling! And the postal service owes these guys much more!
