I don't disagree with what you are saying but the shortage of labor excuse is getting worn out.
I know, that's the 1 thing that I think really has screwed things up the past 2 years during the pandemic is it has given people more leverage to do sub-par work or stick with something long enough to get good at it if they don't like something about it. "Don't like the quality of my work? Well good luck finding help to replace me" seems to be the mindset of too many these days. Just look at how difficult it has been to staff retail, restaurant, and hospitality jobs now let alone be able to hire and keep people that will actually do a good job. It was maybe 3 years ago or so that you saw McDonald's workers walking out and protesting over wanting $15/hour and now most fast food places are hiring for that or more and still can't get enough help. I hear of people saying they will quit their jobs if they are asked to work in the office again when just 2 years ago working from home was not even an option before the pandemic. Just getting the ability to work from home around 50% of the time going forward when it was not even an option previously apparently is not good enough for some it seems.
I know I have gotten frustrated at work in the past couple years that they removed most of our feedback channels where we could provide information to groups that sent work over to us that have the resources and knowledge to do the work themselves without escalation or incorrectly routed something to us that was not in scope of the work we do. Certain management appears to be more worried more about volume and time analytics than they are developing employees that do quality work by using that feedback from mistakes made to coach them up a little to not continue to make the same mistakes going forward. Kind of see the same thing going on with officiating over the years too, they don't want to run a bunch off if they tried to make them more accountable for their performance. It's frustrating to me because if I mess up I own up to my mistakes and not take offense if my management brings it to my attention to correct it or work on something so I don't repeat the same mistake. It's almost as if some people are scared to hold someone accountable for their performance because they think just passing the issues on down the line for someone else to deal with is easier than confronting and correcting what is wrong.
