Do I really want to know how much money other people make?
myDanwei.com claims that they have the salary information for over 200,000+ positions throughout the country. "Danwei" is the Chinese term for organization.
On the one hand, if I was job hunting, this may be a useful tool to help negotiate my new salary. This tool could also give me leverage if I found out that I was severely underpaid and want to ask for a raise.
On the otherhand, if I was severely underpaid and wasn't in the market for a new job, this might make me feel the injustice of being unfairly compensated and motivate me to start job searching. However, it doesn't account for whether the person who was paid more has been in the industry longer or possesses certain skills that warrant the higher salary.
All in all - transparency of information should level the playing field and give more power back to the employees.
I'm just glad that I'm neither job hunting nor underpaid.
Another company,
Wetfeet.com, also give company salary data, but it's on a subscription basis. At $9.95 per month, I'd rather just stay ignorant and happy with what I already have.
