In my experience, I have often been the one taking on more responsibilities when necessary, even though at times this meant a very uneven distribution of tasks within the team. For me, equality in the team means that we are all prepared to take on as much as we possibly can, and not that we distribute the responsibilities equally irrespective of how much each person can take. I like working with less experienced team members, letting them take on as much responsibility as they can, and I also like working with experienced trainers where I can afford to focus more on the content than the procedural and technical aspects of the training.
