Brace yourself for some hazing. "Men want to test women," Rivera says. "I call it the can-she-take-it test. They tease and can be a little crude most of the time, a woman can tell the difference between that kind of behavior and sexual harassment." Annoying, but nothing to make a fuss over. "Suck it up and move on," Rivera advises.
Go ahead be a bitch. Rivera warns of women so afraid of being labeled a bitch that they go out of their way to be accommodating. The result: Male colleagues invariably take advantage of these well-meaning saps. "Don't be afraid to stand up for yourself and say no to things. Some men are going to call you a bitch no matter what you do," she says.
Do not cry. Ever. "It's the ultimate no-no. Nothing will destroy your credibility faster," Rivera says. She advises women to leave the office for a spell if it means avoiding shedding tears in front of colleagues. Whatever it takes, keep your composure.
Find female allies fast. Working exclusively with men can quickly become infuriating the bathroom humor, the alpha-dog bravado. Women who don't have a support system tend to lose their cool with the wrong people and come across as lone wolves. "It seems really obvious, but find a female buddy if you don't want to burn out," Rivera says.
