I was going to say similar re the training, if your place is similar to mine it isn’t exactly training, more shadowing a coworker. In our store we don’t get given extra time to train people so it’s more “pick it up as you go along” thing, it’s not particularly fair on new starters IMO but most people will have been through the same.

I understand what it’s like being sensitive, feeling vibes etc and getting stressed out. I’d say working on managing that might help you. Honestly these days I let a lot go, I kind of switch off if that makes sense, and believe me I’ve worked with some challenging colleagues. There have been days when I’ve been focused on my pay cheque - or something nice I’m going to do later in the week, retail can be a slog especially at this time of year.

I wouldn’t worry about Black Friday, I’d agree that’s almost certainly because you’re not fully trained up yet - I’d count my blessings!
