Have a Legitimate Business Purpose to Search

The U.S. Supreme Court’s “reasonableness test” has been used to balance legitimate business needs with a public sector employee’s expectation of privacy in his own office.1 Though O’Connor v. Ortega applies only to public sector employers, it is a good indication of the test that courts will likely apply to private sector employers. The test focuses on whether:

  • Reasonable grounds exist for suspecting that the search will reveal evidence of work-related misconduct
  • The search is necessary for a non-investigative, work-related purpose, such as looking in an employee’s desk to find a work-related document on a day that the employee is out sick
  • The search’s scope was reasonably related to the search’s objectives and not excessively intrusive in light of the nature of the suspected misconduct

A federal court applied this test to workplace technology in Williams v. Philadelphia Housing Authority. In that case, a supervisor removed a computer disk from a public employee’s desk while he was on leave. The supervisor then read the information on the disk to locate work-related documents and discovered it also contained personal documents. The court held that it was not unreasonable for a supervisor to enter an employee’s office to retrieve important work-related materials while the employee was on leave. Review of the personal documents on the disk while searching for work-related material was not considered unreasonable.2 Though this case dealt with a public employer, it is an excellent example of how the courts will balance competing rights and will likely become part of the precedent applied to private sector employers.
