Several other fallacies may fit, depending on how the reasoning goes:
Red herring – introducing a second argument in response to the first argument that is irrelevant and draws attention away from the original topic. In this case, the original argument is made about poor working conditions in this particular company, and the distracting argument brings up poor working conditions elsewhere.
Appeal to emotions – bringing up emotionally charged facts (starving children, sweatshops) which serve to distract from rational consideration of the original argument.
False dilemma: telling you can either be concerned about your own conditions, or conditions of people who "have it bad", ignoring the fact that you can perfectly care about both at the same time.
Fixed pie fallacy (a.k.a zero-sum fallacy), where the reasoning is based on the assumption that there is a fixed amount of wealth in the world, so by asking more wealth for yourself (more food, better working conditions) you necessarily take those things away from someone, in this case, from people in poorer countries.
