Answer to Question 1
Answer: Companies traditionally hire temporary employees for two reasons. First, temporary workers fill in for core employees who are on approved leaves of absence, including sick leave, vacation, bereavement leave, jury duty, and military leave. Second, temporary workers offer extra sets of hands when companies' business activities peak, during such times as the holiday season for retail businesses or summer for amusement parks. Temporary employees perform jobs on a short-term basis usually measured in days, weeks, or months.
Companies have been hiring temporary workers for three additional reasons. First, temporary employment arrangements provide employers the opportunity to evaluate whether legitimate needs exist for creating new positions. Second, temporary employment arrangements give employers the opportunity to decide whether to retain particular workers on an indefinite basis. In effect, the temporary arrangement represents a probationary period, when employers observe whether workers are meeting job performance standards. As a corollary, such temporary arrangements provide workers the chance to decide whether to accept employment on a full-time basis after they have had time to check things out. Third, employing temporary workers is often less costly than employing core workers because temporary workers are less likely to receive costly discretionary benefits (e.g., medical insurance coverage).
