Pros
Less spoken of elements of the job. You will become connected to the pulse of the nation, you will know what is happening not just locally but globally. You are a fly on the wall and you hear all the gossip and all the news. You will laugh at the nonsensical way people speak and the way it makes you have to speak in turn. You will learn things about people in such intimate detail that you feel like you know them without them knowing you exist. You will be enriched beyond helping the hard of hearing have conversations. If you speak clearly with a smooth voice, it's the easiest job imaginable and being so connected to current events is indescribably amazing.
Cons
You will be forced to hear and repeat every awful thing that people say in private to each other, you will have to engage with opinions that are the opposite of your own because you must be verbatim. Every stutter, every nervous laugh, every repeated element spoken to a person that is hard of hearing or entirely deaf. You caption for the person the caption hardware phone owner is speaking with, they often don't understand or care about the struggles that the phone's 3-8 second output lag causes the caption phone user. Everything wrong in your life will be echoed by the conversations, if you are stressed, your woes will be spoken about by those on the phones, mirroring your worries. This job is best suited for those that live care free lives who will not be dragged down by it, and done for no more than two years as tolerance for whatever set of things that annoy you in the job will only fester inside and turn the most dedicated customer service guru into a seething, muttering curses, hateful person during those calls. You will also suffer hearing loss from extremely loud noises, these can be mitigated very slightly but the company will never mention it, acknowledge it, or question why some of the client function noises are so excessively loud compared to the often quiet conversations. Company gives no raises unless forced to by state minimum wage, but they will lay off a state's whole agent workforce when they go above a threshold of cost, around 14 dollars for a captioning agent. For those working in very low minimum wage states, there are agents doing your job elsewhere making far more than you, but they will be fired as more of your state is drawn from. You will be fired when the automated captioning client is finished and working well enough.
