Adjusting to a new workplace culture is one of the biggest challenges faced by new hires, employers say.

In a recent survey of 250 advertising and marketing executives by The Creative Group, a Menlo Park, Calif.-based staffing services firm, 42 percent said the hardest part of starting a new job was fitting into an unfamiliar workplace. Other hurdles included learning new business protocols, adapting to a manager's style, and being accepted by other staffers, the survey found.

"New employees should pay careful attention to things such as how and when people communicate, and try to emulate the predominant style," The Creative Group Executive Director Megan Slabinski said in a statement.

To avoid rocking the boat, new hires should strive to gain the trust of their co-workers, while sorting out the chain of command and workplace ethic, Slabinski said.
