Downvoters: Consider the context of this thread... Imagine you're asked to train your peers for no extra compensation or credit, and you're still expected to produce 100% of the typical work output. At the same time, your peers are compensated at the same rate, are considered equally for raises and promotions, but are not expected to train anyone.

I understand that senior devs might mentor juniors, or that experienced devs might train up newbies, but to expect one dev to "step up" to mentor teammates without some kind of recognition or compensation is not reasonable. (edit: Especially if those teammates are a long way from being qualified to do the work.)
