I've been at the same company now for 8 years. Over 8 years you can imagine that I have developed quite a bit of equity with the company over that time. In the past year I've turned down multiple promotional opportunities due to the fact that they would be interfering with my real passion RE. They wanted me to take positions that would include a lot more travel and prestige in the company but the $ per hour when all said and done is lower. In many companies if you don't tell them to "hit the brakes" you'll find yourself moving up that corporate ladder with no time to pursue RE.
I finally told my bosses what my goals are outside of work with RE. I prefaced the conversation with the fact that these activities were pursued exclusively outside of work hours. Though it is hard for some to understand that "the ladder" isn't everybody's end game they complimented me on my drive and promised to revisit me in 2 years with these same opportunities to see if my mind had changed.
If you have a good reputation at your job/company I believe you should share this with people you work with. These same people could end up providing you with private $ when you break out on your own.
