Pros
The site itself, and its history, is absolutely incredible. Eastern State Penitentiary is one of the most fascinating historic sites in America, and getting the opportunity to dive deep into its complex history is wonderful.
Cons
The managers at Eastern State are the worst I've experienced in ten years of working as a tour guide at historic sites. They know that hundreds of people want to work there so they treat all of their employees like cattle. They actively look for ways to undermine your confidence and make your day as miserable as possible. They do not care about you at all. The pay is terrible, and you may have to work for as long as a month before you actually receive a paycheck. The site posts an ad for tour guides every few months because the staff turnover is huge due to the incredibly hostile and disrespectful management. Even though it is not in the job description, you really are expected to work a huge amount of after-hours events. If you don't, be prepared to be ignored and have your regular work hours cut down as punishment for not wanting to do extra work. You are also guilted into donating a portion of your paycheck every month to support restoration projects. If you do not, they will find ways to take it out on you. I can't stress enough how unpleasant, self-absorbed, and vindictive the managers are at ESP. They will destroy all of your confidence in yourself. Years later, I still have nightmares that I'm working there again. This is by far the most toxic work environment I have ever experienced, and I would advise everyone to avoid applying for a job here. You will start your job full of excitement and they will turn you into a miserable, dead-eyed robot.
