The term 'SUBS IN OFFICES' refers to temporary workers, or 'TEMPS', who are employed to fill in for regular staff members when they are absent. TEMPS are often used to cover short-term absences due to illness, vacation, or other reasons. They can also be used to fill in for longer-term absences due to maternity leave, sabbaticals, or other extended absences. TEMPS are usually hired on a contract basis and are not considered permanent employees.
