Pros
This is a good part-time job for those who are still in school and those who don't like working retail or customer service jobs. They have multiple shifts (ex. Twilight, Night, etc.) so there are ways to work around your busy schedule. You receive health, vision, and dental benefits. Also, package handlers and drivers are apart of the Teamsters union.
Cons
This is a strenuous job and you will be sweating. Keep hydrated. Take it easy the first couple of weeks, let your muscles adjust and don't over do it or you may get injured. Be prepared to deal with minor bruises and scratches from the job. Work environment is noisy and dirty (very dusty, wear a mask and gloves). Low pay, especially the first couple weeks when you are paying off the Union initiation fee. After taxes and union fees expect to take $100-$200 a week.
