What does it mean when a job saids casual per diem?

When a job is labeled as "casual per diem," it typically means that the position is not permanent, and employees work on an as-needed basis without a guaranteed number of hours. "Per diem" often refers to being paid a daily rate for work performed, rather than a salary or hourly wage. This type of employment offers flexibility for both the employer and employee, but it may also come with less job security and fewer benefits.
