Employees have the right to choose who will represent them in disciplinary or investigative matters, as long as the choice does not violate rules regarding Executive and Administrative Schedule (EAS) or Craft representation.

Employee Representation (651.2):

Subject to prohibitions regarding Executive and Administrative Schedule (EAS)/Craft representation, employees have free choice of representation. Representatives designated by employees, if postal employees and if otherwise in a duty status, are granted a reasonable amount of official time to respond to notices of proposed disciplinary action, to prepare for and represent the employee at a hearing held in accordance with 652.24, and/or to represent an employee who has appealed a letter of warning or emergency placement in a nonduty status in accordance with 652.4. Employees covered under these provisions may request representation during investigative questioning if the employee has a reasonable belief disciplinary action may ensue.
