Pros
The best thing about working for PETA is that you know even your most challenging tasks are going towards benefiting animals. Staffers are kind, polite, and overall friendly people (there are also frequently friendly dogs around if you work in an office). You get to learn a lot about how an international organization functions just from working in the organization--even if you aren't in a media role. The managers genuinely want to utilize and embrace your talents so if you'd like to do work outside your role, managers are often willing to work with you to get proper training and help you. Also, the staff is very diverse in culture and is very sensitive and respectful of individualism.
Cons
Sometimes it can get emotionally overwhelming to see footage and pictures of animals in distress. There is no "getting used to" to some of what PETA investigations uncover. It can be depressing, but it is uplifting to be surrounded by people who are actively determined to make a difference in the issue of animal cruelty.
