No sir, not for a pay cap.
If anything I wish more of us were compensated based on an individual performance vs being lumped in with everyone, as in team performance structure where leeches coast on backs of hard workers.
As for projects/managing the workload, ordering supplies-dealing with vendors and what not I hear you. Done some of that managing at a large warehouse with 5 teams, 85 people I was responsible for. Inbound/outbound - 24/7 operation. Jumping in and helping out with anything/everything. Always short on able bodies, increasing work load, appeasing bosses in Cali and local client we were servicing. Not a stranger to 60 plus hour work week, some weeks closer to 80.
As for upper personnel pay rates, tie it to their performance as well. Company does well, they do well. Run the company into the ground, get 0. Not an atta boy.
