     When you're an employee of a company, no matter the size, it's common to see co-workers

promoted, or transferred to a different department. But there is another way to move around-by

creating a new position for yourself. I did this several years ago, though I wasn't actively looking

for a different job.

     In 2007, I was hired at the Transamerica Life Insurance Company, as a customer service

representative in the distributions services department. I processed requests for distributions from

our annuity(养老金)policy holders around the country. Someone might have forgotten to sign a

form, for example, or might have omitted security information. To solve the problem, I'd mail the

person a letter.

     The company had been through several combinations, so in our department alone we had a

collection of about 140 templates(模板) for letters related to distributions. The longer I worked

with the letters, the more I saw how they could be improved. Some had overlapping information

and could be combined. Some had incorrect grammar or needed updating. I also noticed that industry

terminology(专业术语) wasn't standard across all the versions.

     When I told my department supervisor about this in 2008, she agreed that the letters needed

revamping. She said I should stop what I'd been doing and start the new work. In a relatively short

time, I was able to make numerous improvements and reduce the number of letters to 70. It was an

informal job change until a managers' meeting several months later.

     At that meeting, a vice president who was unaware of my new work mentioned that the division's

entire stock of 1,700 letters should be reviewed. My manager told her that she knew the perfect

person for the job-me. The position was still considered temporary when I took on the extra tasks,

but I was able to show that the work had value, and I was officially promoted and given a raise in

November 2009.
