A Speech Pathologist Per Diem job is a flexible, as-needed position where a speech-language pathologist (SLP) provides evaluation and treatment services for patients with speech, language, voice, or swallowing disorders. These roles are typically in hospitals, rehabilitation centers, or schools and do not follow a fixed schedule. Per diem SLPs may cover staff shortages, vacations, or periods of high patient demand. Because the position is not full-time, benefits may vary, but it offers flexibility and varied work experiences.
