For me, I would say it's about recognizing each person's strengths (and weaknesses). I worked with a very tight group who learned these things about our co-workers. At first, it did take open communication to get there. Within our organization, we respected each other (it just turned out that way. . . the company had thrown together a department with haphazard people who did have the 'respect' idea in their brains).
After a while, we actually didn't need verbal communication anymore. A job would come up, and nothing (at all), being said, I knew that was my job. Another job would come along, and everyone knew (without a word between the team members), that Monica would take care of that. I'm not saying we didn't talk - indeed we did! - I've got three life-long friends from that 10-year job!
The equal contribution thing is kind of a throwback to - you guessed it - Communism or Socialism. I'll do the accounting/math stuff and some of the physical stuff if need be. It doesn't mean that I disrespected the older lady who did occasionally take advantage of my willingness to take on some of her books occasionally. Equal contribution is a dead-end - can't be measured.
I wish I could have valued the company's willingness to allow me to call in sick when I was indeed sick. But, eventually, I had to force my contractual right of them with that one.
Oh, boy LOL I could go on and on . . . Hope some of my thoughts help you though
