Business Ethics question?

Moira recently graduated from college and landed her first corporate job. She works as an Administrative istant for a company that manufactures home decorations. On the job only four months, Moira feels as though she is already starting to lose her idealism about business. She has heard of many instances of employee theft and has even witnessed a couple of occurrences. She has observed employees coming to work intoxicated - even sneaking drinks at work. She has seen employees routinely arrive late for work and sneak out early. Fifteen minute breaks and 30 minute lunches often end up lasting twice as long. Employees routinely use their computers for sending and receiving personal emails, shopping online, checking horoscopes and the weather, even gambling. And all of this is happening in just her department. The dept. manager is very laid back. Moira has tried to talk with him about the problem, but he seems unable or unwilling to confront the problems. It appears to Moira that he wants the employees to like him, and the the employees are taking advantage of that. Moira is growing more and more frustrated, she prides herself on being a dependable, hard worker, and she took this job uming that the other employees would b that way. Moira is tempted to guve up and join the other employees, getting paid for doing as little as possible, but she knows she wouldn't respect herself. She is tmepted to go over her manager's head to his superviser and complain about the problem. But that would alienate her superviser and the other employees. She has not been at the company long enough to request a transfer, and quitting her job is not an option. She is wondering what she should do. What do you think Moira should do?
