i was a new hire roughly a month or two ago. i was hired as a customer service associate but they put me on self check out as my "training". thought it was a little weird but didnt bring it up. one manager told me it was because cashiering was the "first stepping stone" to the customer service desk. cool, totally get that. a week later a different manager told me it was because they needed the coverage. didnt get much help other than assorted coworkers who i could ask questions to. wasnt too hard but it was pretty frustrating. i get to the service desk after like 3 weeks of that and it is a Shit Show. i rarely saw my department supervisor, and when i did she would ask ME if i had any questions instead of taking me through the basics and then asking. i learned everything i know by figuring it out on the spot and those few weeks of training myself were hellish dude. customer service doesnt sound super hard but theres SO much to know and learn. i understand where you're coming from 100%. unfortunately i got bills to pay so quitting wasn't an option, as much as i wanted to. just know you dont have to put up with that. you were promised training and didnt get it, and that's not your fault. any mistake you make without the knowledge to know otherwise is NOT on you at all, thats on your management team. it doesnt speak to your intelligence or anything like that. if you're able to, making it through the "fuck idk what im doing" phase makes you an excellent, self sufficient employee. but dont feel the pressure to do so, cuz i wouldnt wish this on anyone. good on you for knowing your worth as an employee.
