It was an awesome job and everyone was very welcoming but they randomly said they had someone come and say I ran into something. I would of reported it immediately of course I've worked in warehouses for awhile. They wanted to send me for a drug screening not even 10 min before the place closed, no way I could have made it. I called them back they sent me a message and said how did I not make it on time they told me to take it at 1. I have the messages and time stamps. After I couldn't get anyone to answer my calls emails or texts. Shortly after I received a letter stating I quit without notice?
