“Respect for People” is a great short hand statement. There is a great deal of complexity packed into those words.
At the simplest level respect for people requires systems that are designed with people in mind – systems are not designed as though robots were doing what people did. Then those systems also must be built in a way that respects the inherent value of people.
And the idea builds beyond that and grows into an understanding that in order for human systems to be most effective they must engage people. There are significant limits to how effective systems with people can be if you act as though people are just robots to implement the instructions given by some boss. Respect for people moves from being about just the inherent value of people themselves to a principle to allow organizations to be most effective.
Within these principles are all sorts of shades of grey where the principles shed light on ideas to consider but it becomes challenging to know what the specific situation calls for.
Things also get complicated with the way English works. There is another aspect to respect that has to do with having confidence in someone’s ability or maturity.
You don’t show more “respect for people” by overestimating them. If someone does not have the statistical skills to do a task it isn’t a failure of “respect for people” to acknowledge that.
I find myself making decisions on how to treat people differently based on what can be seen as different “respect” (in the respect = confidence in their capabilities and their self-confidence). With some people I can simple say, no you are wrong in this case it is best to do x, y, z. I find this is what I can do with those I have the most of the “respect” for their emotional intelligence.
