Businesses do this shit all the time. There are rules and guidelines that must be ignored for the job to work smoothly. They exist to cover the ass of the employer if something ever goes wrong, they say "due process was not followed" and move on.
What are some of these rules at your place of work?
Obviously don't, erm, dox yourself or anything please.
I worked at a job where it was absolutely verboten to conduct training.
We were hired without any experience, assigned solo projects, advertised as world-class, contracted out as skilled experts, and berated harshly as well as rewarded based on performance.
Our manager told us an angry client had said "what, do you have bus boys doing this work?" and our manager was retelling it like he thought it was a ridiculous and offensive thing to say.
No, the client isn't accusing you of handing work to your bus boy in between water refills- he's accusing you of hiring bus boys, which a fifth of the staff literally was before this job, because that is outlandish and ridiculous for the expensive services we are selling. You hired an actual waiter and put him on this specific client, and didn't train him, and that's the reason this specific work was so bad. The client is exactly correct but he doesn't realize it
