Is it a good idea to share your salary with your coworkers? The intent being to support each other with salary negotiation? Or will it always backfire. Please cite real-world examples.
In theory it is a good idea to be open about your salary. This protects people from being screwed and helps companies be more fair with the pay. As for real world examples often in gender pay gap discrimination cases people don't really know they are being paid less than male coworkers. Here is just one case though it did not specify how the person found about the salary, but it wouldn't have hurt.
This is all in theory though. Some people might feel resentment having people get paid more than them. Some might judge others on not making as much. One thing that is for sure is it is always in the employers favor for the employees to have less information about how their coworkers are compensated. It really depends on how open your coworkers are and how open you are to sharing information.
Some people are remarkably sensitive about money and some aren't. Personally, I've found sharing my salary to really help my career (I was getting paid less, doing the same or better work and used my newfound salary info to ask for a raise, which I got). Specifically, I was earning 100k (which I was really happy with at the time) to find out people in the similar role with similar experience were earning closer to 120k. I used that info to talk with my manager about how based on my recent successes I deserved a raise and they granted it to me. That being said, I was working my butt off and being a real team player so I'm sure that played into it.
Othertimes, I have noticed some friends getting uncomfortable or resentful when I discussed earnings with them. Especially if the gap between our incomes was larger than 10 or 15 percent.
At the current company I work for, we are large enough to have a (employee created) anonymous database of reported incomes based on role, seniority and location. It's super helpful. I'd recommend that as the best approach for someone who is interested in learning more about the 'paybands' at their company without having to worry about making anyone feel uncomfortable (since it's anonymous).
I believe there is another, one may say ingenious, solution to your problem. By working as a team with your fellow coworkers, you can strategically use the knowledge of what you all make to negotiate everyone’s salary. However, at the end of the day, you and your coworkers combine what you all make and divide it amongst yourselves evenly. The trick is that your employer cannot have any idea that this plan is taking place. In his or her eyes, they will think that these individual negotiations imply that they have created a healthy, competitive work environment, when in reality, it doesn’t matter who makes what, just as long as someone is getting a raise, everyone wins.
My coworkers and I started doing this about 8 months ago and it’s honestly the best case scenario. I haven’t had to work one lick harder, yet I’m making a great deal more than before. My boss seems to be pleased with how “hard” we work and it has brought me closer to my fellow comrades.
Real World Example : Check your contract.
I have had experiences with organizations where the contract explicitly mentions that all matters related to your remuneration and compensation is confidential between you and the organization. Employees were only allowed to disclose the particulars of the contract and salary revisions only with the authorized personnel (HR Executives, not even reporting manager). By sharing that information publicly, therefore, you'll be breaching the terms.
No one can stop you from having over-a-beer chat with your friendly colleague about the range of the compensation overall and your expectations, but make sure you do not do anything that can be used to determine a particular number and traced back to you as breach of terms.
Otherwise, if there is nothing specific in the contract that prohibits you from disclosing the information, use your best judgement on what an how much to be shared.
