They call her C.C., a chance nickname that because a career bonus.

"My grandmother thought Cecelia Colette was a little pompous for a kid," recalls training consultant C.C. Bronder. "I can't tell you how may groups have been shocked to find that their keynote speaker, Dr. C.C. Bronder, is a woman,"

Bronder, 36, had Ph.D in mathematic curriculum and supervision and worked her way up from high school teacher to assist dean at the University of Pittsburgh. In one career jump she moved from TWA flight attendant to manager of sales and service training.

She is now teaching other women how to climb the corporate ladder through nationwide seminars on Women at Work. She is the only female faculty member of Fred Pryor business seminars -- an inequity she says she's working to change.

Fatigue, she says, is the major problem facing future business giants.

"I see women putting in a full 40 to 70 hours on the job, then coming home to housework and kids." In her recent seminar before a cheering audience of 164 women and one man at the Hyatt Regency, Bronder advised women, first, to give up "the Wonder Woman myth."

"It's an exercise in self-abuse. Stop feeling guilty and don't expect perfection in all your roles. Get your priorities clear. Chances are we'll be living in messier homes than our mothers.

"Communicate with our family members and discuss who will be responsible for what. Hire someone else to do some of your work. And leave some time for yourself or you'll burn out too quickly.

"Take your child to work with you. Explain how life is better with your income than without it, and tell them why work is important to you. Get other people to share in the responsibility of parenting, sich as grandparents or neighbors (for whom you'll return the favor)."

Bronder also noted some typical regional problems women face.

"The Southern male is a whole lot slower to change than the Nothern male," she says, In California, the single-mother pattern came out loud and clear.

"In D.C. women in government feel especially oppressed in trying to beat the system that is so supportive of men. Particularly with veterans getting preference."

She offers this advice for women who want to advance in business:

Communicate Authority

Start picking up tabs. "Stop letting yourself be taken care of. It will make you feel very powerful to be able to take care of someone else."

Become a handshaker. "It won't happen unless you initiate." Plant your hand firmly in the person's palm, look him or her in the eye and state your name, plus memory-jogging statement, such as "Carter, like the president."

Carry a briefcase . "Briefcases are very powerful. But don't carry both a briefcase and a purse because it makes you look confused."

Dress conservatively .

Get and use business cards . "Important people have them." If you aren't particularly proud of your present job title, just use your name, address and phone number.

Gain Support

Establish credibility . Keep promises, return phone calls, follow up suggestions and be prompt for meetings.

Get results . Do your job well and keep a protfolio of accomplishments. Head up a project and quantify the results by figuring how much money, personnel and/or time was saved.

Break into the old-boy network .When "the boys" go out to lunch, assume you're invited rather than assume you're excluded. Join professional organizations.

Find a trusted friend . Seek advice from a peer or senior manager who will challenge you and help you in your career. If you've had a mentor on your way up, serve as a mentor to an up-and-coming woman.

Think Big

Take risks . Avoid the temptation to stay in a secure, familiar job rather than chance advancement. Think of your work as a career, not just a job.

Be comprotable with big numbers . Get used to dealing with large figures and dollars.

Think in terms of the whole company . Get an umbrella view of your company's goals. Continually think in terms of the organization's perspective and avoid inter-office quibbling.

Set goals . Forty percent of people who think about goals, 80 percent who write them down, and 90 percent who talk about goals reach them, she contends. Figure out where you want to be in six weeks, in one year, in five years. Take an hour a day for the next six weeks to work toward some goals and then revise and reassess them regularly.
