I worked at Uline full-time (More than a year)
The pay was decent with giant bonuses at the end of each year. You will always get your 40 hours.
Schedule is strict. No upwards advancement from within the company. Good ol boys system is in place. Required to purchase sleeves for your arms to hide any and all tattoos. Long hours using windex to wipe down racking.
Advice to Management
Look for your internal talent before hiring from outside the company.
