This is highly country dependent, but in America for example, if this is not presented in your employment contract then it is not something your employer needs to do.

However, if your employer is a public organization then all of this information needs to be made available to shareholders. While you may not have access to this information, it is not secret and can be shared by any of the shareholders. Due to this, there is an implicit requirement to reduce risk and “cooking the books” while allowed is generally seen as risky since shareholders may run for the hills. In a smaller, privately run company there are no shareholders to run for the hills. Just a bunch of employees who hold paper IOUs. In order to get that audit protection, the employee would need to negotiate that into their employment agreement!
