I get a lot of email from people who are 50 years old and older and never expected to be unemployed at this stage in their career. Many of these people are annoyed that they are not appreciated for how much they know. Others are bitter, angry or indignant. Often times, these complaints come down to one thing: age discrimination.

Hiring managers know they shouldn’t discriminate based on age, but they do it anyway. Even when the victim has proof, usually a lawsuit is not as appealing as just getting a job. Ridding the world of injustice is a luxury for those who do not have trouble paying their grocery bills — now or during retirement.

I have not experienced age discrimination, but with sex discrimination I have found that bitterness and anger only hurt me. I am certain I have missed opportunities because I am a woman. But in my early twenties, when I was bitter and angry about sex discrimination, I was bitter and angry wherever I went. And my unpleasant personality hurt me way more than any lost opportunities.

Most hiring managers do not discriminate against women, or older people, but all hiring managers discriminate against people who are angry and bitter. And they should, because angry, bitter people are difficult to work with. So if you want to get a job, you need to stop being angry about the fact that people discriminate against you.

It’s very hard to hide anger and bitterness – they poke out of any little opening they can find. The fastest way to get rid of them: Convince yourself that most people are basically good, and when you encounter an asshole, assume he's an aberration and move on.

I have spoken with recruiters about age discrimination, and recruiters say that age is not an issue if the candidate does not make it an issue; enthusiastic, curious, and ambitious candidates are gems no matter what the age. But some candidates don't want to work for someone younger than they are. Some candidates can't hear constructive criticism because they assume it’s ageism. These people are doomed in the job market because they come off looking bitter. Before you cite ageism, ask yourself who, really, is making the big deal about your age.

My mom is a great example of someone who has overcome the age barrier. She is almost 60 but re-entered the job market at 50. She has received many promotions and she loves her job. I am convinced that her success is due, in part, to the fact that she is never angry about being old, and she is never bitter about reporting to someone twenty years younger than she is.

While my mom is just one person, she is a good example. She has a lot more experience in life than the people she works with, and she could lord that over people in a you-can-learn-from-me way. But instead she focuses on things that are new to her — what she can learn, what she can accomplish. In that way, she conveys the bright-eyed excitement that is essential in an enthusiastic employee.

So if you want to beat discrimination, try to ignore it. I am not suggesting that ageism is okay. It's not. But it exists, and you need to figure out how to get a job in the real world. So accept where you are in life and embrace that. If you are pleased with who you are then you will have a much easier time convincing a hiring manager that she will be pleased with you.

For all of you who are disgusted by the rampant discrimination that really does exist, I have found that the best way to change workplace culture is to infiltrate. You can't change workplace culture by whining from the outside, but you can change it once you are part of it. I have always used my positions in management to hire a diverse staff. You can promote diversity, too. Once you get a job.

My dad just called. He said one of his fifteen-year-old students asked, “Why do we need to know this? How will To Kill a Mockingbird help me in life?” My dad loves questions like that because he has asked them himself.

My dad has always loved school. He was the kid who did the extra credit even though he already had an A. So he had a lot of options at the end of college. He applied to two graduate schools: Yale for history and Harvard for law. He got into them both.

Before I tell you what he chose, I have to tell you about my family. Rich. Mob money. My great-grandfather, my dad’s grandpa, was the lawyer for the Chicago mob: solid work during prohibition and a reliable profession during the depression. Money flowed freely during my dad’s college days, but his grandfather threatened the inheritance if my dad chose history over law. The way my dad tells the story, he always knew he wanted to teach, but he was scared to risk his family “?s wrath, to say nothing of their wealth.

So, after Harvard, my dad went to the top law firm in Chicago (without even having to interview.) My dad hated it, but he wasn’t a risk taker, so he hated it for a long time, thinking the money was worth it. Like the BMW: he drove one of the first cars (when the motorcycle company diversified in desperation) and the cars were so rare that the BMWs would flash each other when they passed. (I’d yell from the back seat, “Hey, there’s one! Flash, Dad, flash!)

There came a point, though when my dad asked himself, “Why do I need to know about all these cases? How is this helping me in life?” His grandpa died, his law firm merged, and the bottom of the BMW fell out.

Finally, after years of thinking his career would get better, it didn’t, and he quit. He went to graduate school to teach high school history. He was older than all the professors. His kids were older than all the students. After thirty years of practicing law, he started over.

I asked him about classes and he’s say, “It’s hard to go back to school. It’s hard to no know what I’m dong after so many years of doing the same thing.” He said his favorite class was the history of civil rights, because when they got to the ’60s he could write papers about his college days.

Upon graduation, everyone in his class got interviews and he didn’t. No one even talked about age discrimination because it was so obviously there and so obviously unavoidable. Finally, though, he got a job. Teaching English. He wanted to teach history, but he’s entry level now. It’s like doing HTML when you’ve got a degree in computer science.

But my dad is thrilled. He took a big career risk and he’s happy. He’s happy to be interacting with the students, but also, I have a feeling that he’s happy he took a risk. Changing careers is so scary, but it’s so empowering-it gives you assurance that you can al ways choose to do what you want most — the hard part is to know yourself well enough to know what that is. So think like a fifteen-year-old and ask yourself, “Why am I doing this?” And then think like a risk taker and jump like my dad when you know your time is right.

Each time in my career that I have ignored sexual harassment aimed at me, I have moved up the corporate ladder. For example, the boss who once pulled all senior management out of the company’s sexual harassment seminar because he thought it was a waste of time — and patted me on the butt as he left the room — has turned out to be my most reliable cheerleader (and a very impressive reference).

In my first eight days of my job at a financial software company, I was sexually harassed six times by my new boss. This list does not include his sexual harassment of me during the interview process, which I chose to ignore, since it was my first interview at a respectable company in six months.

Maybe you’re wondering what, exactly, I regard as sexual harassment. The easiest conversation to relay is this one:

Me: “Thank you for setting up that meeting; it will be very helpful.”

Boss: “Big testicles.” (He then pretends to squeeze his genitals.)

I had no idea what he meant by this comment, but it is short and easy to relay to make my case.

Here are some other choice moments:

When he took me out for lunch on my second day on the job, he told me he once fell in love with a woman as tall as I am but was intimidated by her height, so they just had casual sex. I said nothing in response.

But I knew, from a legal perspective (and also a moral one) that I needed to tell him his comments were unwanted. So that afternoon when he said, “I want to hug you, but it would be illegal,” I said, “You’re right.”

Each night, I relayed some of the best lines from work to my husband. He was stunned. He couldn't believe these events actually happened in today's workplaces. I told him this was standard. He told me I should sue so that we could go to Tahiti. I told him I’d probably settle out of court after three years for about $200,000, and I’d be a pariah in the workplace.

I told my husband that his very hot, 27-year-old boss gets hit on as much as I do. He said he saw her at work all the time and this never happened. I told him that OF COURSE men don’t harass women in front of other men. After all, it’s illegal. Men are not stupid. But I suggested to my husband he was perpetuating the myth that harassment isn’t widespread.

In fact, 44% of women between ages 35 and 49 report experiencing sexual harassment at the workplace — even though almost every company has an explicit, no-tolerance policy. A national survey shows that 21% of all women report being sexually harassed at work, while a Rutger's University study indicates that for knowledge-based workers, the percentage can go as high as 88%. Yet when women leverage the no-tolerance policy their names are plastered over the business pages, and they are blacklisted in their industry.

So the best way to change corporate America is to gain power and then wield it. To get power, you have to stay in the workforce, not the court system, and work your way up. Unfortunately, this means learning how to navigate a boys’ club. But when you know the system, you then are clear about the root of its problems, and you know how to initiate change.

In this spirit, I hatched a plan to rid myself of my harassing boss. Originally, I took a job in business development, even though I hated selling to clients, because it was the only place with an opening. I told myself that the members of the management team were so smart that I would learn to love sales from them. After weeks of harassment, though, I thought management was so smart that if I explained why I wanted to be moved to another department, they would see my request as extremely reasonable. I figured they would be grateful for my low-key approach to this sensitive problem, rather than resentful that I had been hired to work in biz dev and then asked to be switched to a department with no openings.

I was right. I was moved into marketing, which I prefer. I received a more prestigious assignment and gained a smarter boss. Had I reported that I had been sexually harassed during the interview process I would not have gotten the job. Had I reported the harassment to my boss's boss without presenting a plan for solving the problem, I would not have received a better assignment. In fact, if you have a strategy, enduring sexual harassment can be a way to gain power to achieve your long-range goals.

Epilogue: Eventually, my boss was fired. Officially for low performance, though I have always fantasized that it was for rampant harassment.
