Those are great questions, and I don't think all answers exist or if there is any base level of agreement between major anarcho-syndicalists. At least I don't know them. Note that there are distinctions between the base salary someone is paid, the share of the profits they get (on top of the salary), and their voting rights. So people with specialized skillsets would likely get extra compensated in salary, maybe in some profits. Otherwise, they can switch to some other firm that compensates them better. Note that the only thing that is being banned is for capital to wholly own the profits emerging from the labor of others. Most other features of the market economy will continue to exist. I don't expect any society that implements an anarcho-syndicalism to be free of "human" problems. Firms will continue to have drama, and politics, and likely people will band together to screw over other bands of people in the same or other firms. These are not visions of a utopia. The attempt is only to create an economic system that has significantly less fundamental problems than existing capitalism. Sorry, I don't have better answers.
