but I’m not entirely buying it as a rational explanation for this.
This literally could go for anything in the Bible. As the person said, the Bible is the word of God, Christians follow the Bible without questioning the word of God. It is, inherently, not based on rational, it is based on Authority.
Damn I felt this in my bones. I am a union organizer at my hospital and those numbers are bang on... Out of a department of 100 or so there is usually me being the union person, and MAYBE I can get 1 or 2 other people to do certain things at certain times, and about 5-10 people to participate in an in person action that isnt a strike... And the other people are happy to get the benefits but dont want to put in any effort or "risk" at all.
We actually did have a 1 day strike 3 years ago and I'd say even then 3-5% of the people crossed the picket line to work, maaaaybe 50% of the nurses showed up in person outside the hospital, and the other 50% just cant be bothered to interrupt their life at all.
We are very tactical with our stuff and it was only a 1 day strike (although it does have ramifications for about 5 days because of staffing contracts)... If it was an open ended strike I bet the number of people that would be active in it would immediately fall to your stated 15% or so outside of the first week
