IF your goal is just to keep your head down and keep a paycheck, your goal is to 1) keep up the appearance of business and 2) be easy to manage. As long as none of you behavior reaches your direct report, you're golden. Try to find someone more experienced with you to show you the ropes and never ask your manager for clarification or support except when absolutely necessary. Instead, rely on your coworkers to train you and try to find some way to make things equitable with them.

Bonus points if you can find what metrics your manager is measured on and work a little to butter their bread. Eventually, you will figure out which areas you can do the bare minimum in and spend the least total amount of energy for the most job security and likelihood of a raise. Do not work yourself to the bone and do not work beyond paid or contract hours.

For instance, I worked in a chain coffee store and found out my manager did not like having to delegate/think about certain cleaning tasks so I would do those really quick before fucking off in the back and that lowered my overall amount of responsibility while also boosting me in my bosses eyes. Of course, if we were really busy I would pull my weight fairly and not throw my coworkers under the bus.
