The term 'worker from an agency' can be summarized as a 'TEMP', which is a four-letter word. A TEMP is a worker who is employed by an agency to work for a short period of time, usually on a project or assignment. They are not typically employed on a permanent basis and may be hired to fill in for a regular employee who is on vacation or leave. TEMP workers are often used to fill in for seasonal or peak workloads.
