I got told twice by the same manager that I will be able to go home early tonight. HA that didn't happen! I like how everyone can go home early except me! I like how I work 45+ hours a week and get nothing from it. My daughter is about to 6 months old and I have to leave her for 14+hours one day every weekend and that sucks!!
