An interpretation letter from the Occupational Safety and Health Administration (“OSHA”) advises that non-union employees can appoint a union representative to represent them in OSHA inspections. OSHA has long recognized that union representatives can represent unionized workers during OSHA inspections. The regulations also allow for a third-party to accompany the inspector if there is “good cause.” This interpretation could give union representatives access to the employer’s facility and allow for employee interaction during organizing campaigns.
