It's been a long time since I've had a job with manual labor, but I remember how annoying a lot of people would be when training and expecting you to be fast on day 1. I'm rewatching Undercover Boss and Bar Rescue and this reminds me of the stupidity of the situations, I get that they're shows but the way people act is how a lot of them acted in real life too.
I get extremely annoyed when they expect someone to be fast on day one, to the point I felt the need to make a post about it. You need to train someone to do it right and the speed will come, just yelling 'do it faster' 'too slow' honestly just makes the situation worse and they start making mistakes. These people act like on day 1 they expect a brand new person to be as fast as the guy who worked there 10 years. What does that say about the guy who worked there 10 years? I just find it completely moronic and mentally roll my eyes every time someone is acting like someone is an idiot for not being as fast as everyone else who worked there for years with an hour of training.
I remember experiencing this at work in the past with a few bosses and you just take it and pretend they're right but inside you know they are dumbasses for having that kind of expectation early on. What's even worse is when the person who worked there a long time developed their own weird techniques that may or may not actually be more efficient but they act like everyone who doesn't do it their way is an idiot.
I'm not counting when people are intentionally hard on beginners to make them work to a higher standard, and then later become softer on the employee, this is debatably a good method and I'm not talking about that.
