When the day is coming to an end, you must go to the briefing room. There you will see a summary of most of your expenses and how your decisions have influenced the respect of both the convicts and your colleagues.
First of all, the summary allows you to analyse which of your actions were considered to be commendable, or quite the opposite. This will help you in the future to keep an eye on your decisions when it comes to resolving a conflict or fulfilling someone else's request. Which side will benefit and which side will suffer? Is it better to keep up your spirit among your colleagues today, or can you afford to get closer with prisoners?
Nevertheless, the financial aspect is crucial, too. You get your daily wage every day. It's your private money that allows you to buy the necessary items for your everyday work... or to bribe someone. But, besides your private money, you also have the prison budget at your disposal. You can use those funds only to buy some things to improve the facility.
If you wonder why a rank-and-file warden has an access to the prison budget...you'll see about that in due time.
