How to Collect Anonymous Employee Feedback in Slack, Teams & Google? [ Step-by-Step Guide for Free]

In today's work world, listening to what employees think and feel is very important. But, the old ways we used to get their ideas aren't working well anymore. 

Imagine this: only about 3 out of 10 workers think their bosses really care about what they have to say. And just as few believe their ideas help make their workplace better.

For those in charge of making employees happy and engaged, like HR managers, founders, or people officers, this is a big problem.

Yearly surveys asking how employees feel don't get many responses, the answers they do get don't tell much, and the lack of data in between surveys leaves gaps in your ability to make continuous improvements. 

Employees are scared that being honest could make things difficult for them at work. Even quick questions or suggestion boxes don't seem to do the job well.

So, how can we make things better and make everyone feel included and happy at work without knowing what everyone thinks?

Thankfully, new technology is here to help. Some smart tools use anonymity and AI (Artificial Intelligence) to make giving feedback easy and safe.

These tools work right in the apps employees already use, so they don't have to bother with new accounts or extra steps. 

This makes more employees willing to share their thoughts. In fact, with these tools, more than 75% of employees from different places and jobs start to share more openly. These tools can also combine team feedback from different sources and assemble it into one automated report saving precious hours in a week.. This helps us find new insights and trends we couldn't see before.

In this guide, we'll show you how these new anonymous employee feedback systems can fix the problems with the old ways.

We'll look at how a smart tool in Slack, for example, can ask quick questions that employees can answer without anyone knowing who they are, making anonymous employee feedback possible. 

Then, we'll see how these tools can look at all the answers to find common themes and how people feel, all without revealing anyone's identity. This means companies can understand and act on what everyone thinks, not just the few who always speak up.

The big takeaway? When done right, asking for anonymous employee feedback without revealing who said what can change everything for the better.

It helps everyone learn faster, come up with new ideas, and feel like their voice matters. This makes people want to stay with the company longer and do their best work. Let's dive in and see how it works.

What Is Anonymous Feedback?

Anonymous feedback allows employees to provide honest and open feedback about their working environment without fearing repercussions. It allows employees to express themselves freely, knowing their feedback will remain confidential. 

This type of feedback helps employers gain insight into how their staff perceives the workplace and can help identify areas that need improvement.

Anonymous feedback refers to perspectives shared without names or identities attached.

For your employees, anonymity is transformative:

  • By analyzing feedback for common themes, companies can gain insights into the overall employee sentiment, allowing them to address issues proactively.
  • This approach fosters a sense of belonging and respect among employees, as they see their feedback being taken seriously and acted upon.

As we delve into the specifics of how these anonymous employee feedback systems work and their impact, it becomes clear that anonymous feedback can transform workplace culture, leading to enhanced employee satisfaction and retention. 

But how can leaders actually enable candid sharing? Practical solutions exist making broad-based anonymous feedback simple and ethical.

How to collect anonymous employee feedback?

Employers have various options available to gather anonymous feedback from their employees. Here are the 4 steps you need to complete to collect feedback anonymously:

1. Select Anonymous Tools

  • Use anonymous survey platforms like Wrenly for direct anonymous communication directly in Slack and Teams.

2. Ensure Anonymity

  • Make sure the tools or methods used do not track identifiable information.

3. Design Effective Surveys

  • Include a mix of open-ended questions and specific queries to gather diverse insights.

Now let's explore the practicality of running anonymous surveys in three popular workplace platforms: 

  • Slack, 
  • Microsoft Teams, and 
  • Google Workplace 

Each platform offers unique features and approaches for engaging with employees and collecting their feedback confidentially.

  • No Ability to Follow Up: Unlike Wrenly, Google Forms does not offer a way for leadership to reply back to individual responses to ask for clarifications, further data, or to give a suggestion.

How to implement an anonymous employee feedback process

Once employers have established a way to collect anonymous employee feedback, they must also ensure they take the right steps to implement an effective process. Here are four key steps: 

Create clear guidelines 

Employers should start by creating a set of policies and guidelines for how employees can provide feedback anonymously. These should outline what types of comments are appropriate and how they can be submitted. Clear guidelines will help ensure the feedback is constructive and relevant and provide staff with a sense of security. 

Establish a system for collecting feedback. 

Employers should also create an effective system for collecting anonymous employee feedback. This could include setting up online surveys, creating anonymous suggestion boxes, or using employee engagement platforms. By establishing a reliable system for collecting feedback, employers can ensure they get the best information from staff members. 

Encourage participation 

Encouraging employees to participate in anonymous feedback initiatives is key to ensuring success. Employers should publicize their efforts and create an environment where staff feel comfortable sharing their opinions without fear of retribution or judgment. This can increase participation rates and ensure employers get honest and accurate feedback from their staff. 

Analyze and act on the results

Finally, employers should analyze the anonymous employee feedback they receive and take action where needed. By examining the responses carefully, employers can identify areas for improvement and create strategies to address any issues. This will help create a better work environment for staff members and ensure they feel comfortable voicing their opinions. 

By taking these steps, employers can ensure they collect anonymous employee feedback effectively and constructively. Ultimately, this will help them gain valuable insights into their workplace and make informed decisions that benefit employers and employees.


In this guide, we've looked at how anonymous feedback from employees can change the workplace for the better. We've shown why it's key to really understand how employees feel, encourage everyone to speak up and create a sense of belonging for all.

We've covered practical ways to collect this important feedback without revealing who said what, using tools like Slack, Teams, and Google Forms. For success, it's vital to be open about what you're doing, communicate clearly, and act on what you learn.

Here's what to remember from this guide:

  • Anonymous feedback lets employees speak freely. It removes the worry of negative consequences, leading to honest and useful responses.
  • Technology makes it easier to gather feedback without revealing identities. Solutions like Wrenly and online surveys help simplify this process while keeping it anonymous.
  • Pick the method that fits best with how your team already works. If your team works in Slack or Teams daily, an integration would make the most sense. If you need to send a survey via email then Google Forms is a great way to go.
  • Making sure everyone knows how to participate is key. Spread the word about your feedback efforts and ensure everyone feels safe to share.
  • Turning feedback into real change needs careful analysis and action. Look at the feedback, spot patterns, and solve problems to make real differences.

By valuing anonymous feedback and acting upon it, you can foster a workforce that is more involved, happier, and more productive. This leads to a stronger company culture, better performance, and keeping employees longer.

Starting to listen to your employees marks the beginning of building a brighter future together. Give them the chance to share their thoughts, and they'll help you make your workplace even better.
