Reporting suspected wrongdoing can put you in a difficult position when a negative personnel action follows. You may wonder whether the action resulted from a legitimate workplace decision or from your decision to speak up. Federal whistleblower law provides a way to examine that connection.
Here is what you should know about the knowledge-timing test and how it may apply to your situation.
How the knowledge-timing test works
The knowledge-timing test looks at two facts: whether the official who took the personnel action knew about your disclosure and whether the action happened within a period that could lead a reasonable person to connect the two events. The test helps establish whether your disclosure contributed to the personnel action.
Under 5 U.S.C. § 1221(e), you can use this type of circumstantial evidence to show a contributing factor in a whistleblower retaliation claim. You do not necessarily need direct proof that an official admitted to retaliating against you. For example, if the official who knew about your disclosure reassigned you shortly afterward without a clear reason, the timing may point to potential retaliation.
How you can evaluate the timing of retaliation
Start by comparing who knew about your disclosure, who made the personnel decision and when each event occurred. Ask yourself:
- Did the decision-maker know about your disclosure?
- How much time passed before the personnel action?
- Did other circumstances connect the disclosure to the decision?
There is no fixed number of days or months that automatically satisfies the timing part of the test. The MSPB has recognized that timing can support an inference even when more than a year has passed. If the timing does not establish a connection by itself, other circumstantial evidence may still help show that your disclosure contributed to the action.
Take a closer look at the sequence of events
If your timeline raises concerns, preserve the records that show when you made your disclosure, when the relevant officials learned about it and when the personnel action followed. Reviewing that chronology with an attorney can help you determine whether the facts support a potential retaliation claim and what evidence may matter next.
