Post Doctoral

Process Additional Pay and Handdrawn Paychecks

For departments paying Postdoctoral Fellows/Trainees in job code 1438

What should happen is a two-step process:
  1. PRIOR to the work being done, the proposed work and additional pay needs to receive approval from the PDO. The clearest and cleanest arrangement is written into an addendum letter and routed for signatures. This enables a review to make certain the agreement conforms to the policies regarding additional pay for research positions, and that it is okay for the postdoc to go ahead with the work, expecting additional remuneration. There's almost nothing worse than an employee's expectation unfulfilled because the department made a promise it couldn't keep -- due to not following policy or procedure properly.
  2. AFTER the work is completed, the APF form is submitted to show it is time to pay the person for the agreed upon work.

Payroll procedures are the same for Postdocs as for most other employees, except the approvals for these exceptions to normal payroll need to flow through the Postdoctoral Office (PDO).

More detailed steps follow below:

Handdrawn Warrants

What circumstances are acceptable for additional pay for a Postdoc? It is possible for a Postdoc to earn additional pay, but certain criteria must be present in the circumstance. Many of these are the same as for other employee classes.

  • It is reimbursement for moving expense – must be stated in the offer letter and follow this policy: Moving.pdf
  • It is part of an official University-sanctioned, employee award program. See this University policy for criteria: Procedures Guide
  • It is for truly additional work, not just added assignments within the regular job's scope. (As exempt employees, all work assigned to the postdoc by the primary job supervisor is considered part of the base position's work to be completed no matter how long it takes.)
    • The work must be completed outside of and in addition to the work hours required for the base position. The postdoc's supervisor must agree to the arrangement to see that it does not impact the expectations of the grant sponsor paying the salary of the base position. (Ex: 100% effort required by federal grants.)
    • In all but exceptional cases, the work would be done in a different realm than the usual lab research that is performed in the base position and included in the job description, or at least must be performed for a different lab and type of project altogether. Potentially, short-term teaching assignments, or performing information technology work that is totally different than the normal research, may be considered.
    • The work must be short-term for a specified period of time and covered in one lump sum or flat fee paid out at the end of the work project.
    • Other PDO-approved items on a case-by-case basis. (Ex.: The Postdoc is part of a project where the funder's agreement/contract calls for attendance at a special workshop that results in a product for the funder and there is a line in the grant budget outlining pay for this very scenario, showing this additional pay is part of the project plan.)



  1. Before trying to process additional pay:
    1. Check the policy for research positions to make sure that the criteria make the postdoc eligible for additional pay. UCD's Administrative Policy "Research Assistant/Associate (PRA) - AMC" has applicable guidelines at Section G.7, G9-13, and K.
    2. Best practice is to contact the PDO prior to sending documents and find out if the transaction is acceptable so that it can be approved. An addendum letter is the best document to put on file for this, showing signature approval.
  2. The usual PBS Additional Pay Form is completed with departmental signatures and forwarded via electronic attachment to the Postdoctoral Office for the Dean's final approval signature.
    1. Make sure the description is complete enough for clear understanding of the reason for additional pay or attach a detailed memo or the addendum letter.
    2. All supporting documents must be attached as HR will require those before processing.
  3. The PDO will forward the form and documents to HR, unless the departmental unit requests otherwise.
  4. Departments need to create a One Time Pay batch for HR to approve before payroll runs for the month. Refer to the PBS payroll calendar for deadline.
  5. It is up to the departmental unit requesting the payroll action to follow through with tracking the action to completion.



  1. Complete the usual PBS form to request a Hand-drawn Warrant , only send it to the PDO via electronic attachment to obtain the final signature.
  2. The PDO will forward the forms to PBS, unless the departmental unit requests otherwise.
  3. It is up to the departmental unit requesting the payroll action to follow through with tracking the action to completion.
