One of the biggest challenges Employers face when running campaigns on Microworkers is balancing quality control with worker satisfaction. A high rejection rate (too many “Not Satisfied/NOK” ratings) can lead to negative feedback from workers, reduce the efficiency of your campaigns, and even harm your Employer reputation. However, with the right strategies, you can minimize task rejections while ensuring high-quality submissions. This article will explore practical tips for Employers to improve task acceptance rates and create a better experience for workers.

Why Task Rejection Matters

When workers experience frequent rejections, they may avoid your campaigns. Thus, causing delays in project completion. Excessive rejections can also trigger disputes, adding more work for Employers and reducing overall efficiency.

Strategies to Reduce Task Rejection Rates

1. Set Clear and Precise Instructions

Many rejections stem from misunderstandings rather than intentional errors. Unclear instructions are one of the biggest reasons for rejected tasks. Workers can only complete tasks correctly if they fully understand the requirements.

📌 Problem: Workers fail to complete tasks correctly because instructions are vague, lengthy, or missing key details.

✔ Solution:

✅ Use simple, clear, and structured instructions with numbered steps. You may also use bullet points for easy readability.

✅ Provide step-by-step guidance. Provide examples or screenshots to demonstrate the expected results.
✅ Clearly state what proof of work workers need to submit.

✅ Avoid vague requirements like “Give a detailed answer” without specifying what “detailed” means
✅ Use screenshots or examples if needed

💡 Example scenario:
An Employer running a product categorization task found that workers frequently mislabeled products. After adding examples (e.g., “A laptop belongs in ‘Electronics,’ not ‘Office Supplies'”), correct submissions increased by 80%.

🔹 Extra Tip: If possible, include sample screenshots or diagrams to make the instructions clearer.

2. Use Qualification Tests for Complex Work

If your campaign requires specific skills, consider running a Qualification test before launching a full campaign. This ensures that only experienced and competent workers complete the main tasks.

📌 Problem: Complex tasks require skilled workers, but anyone can apply, leading to low-quality work.

✔ Solution:
✅ Create a Qualification Test to filter out unqualified workers.
✅ Only allow workers who pass the test to access your main campaign.
✅ Ensure the test is representative of the actual work.

💡 Example scenario:
A business needed workers to proofread articles, but many submissions had errors. They introduced a basic grammar test before allowing workers into the campaign. As a result, task accuracy improved by 75% and fewer tasks needed rejection.

3. Use the ‘Revise’ Feature

Mistakes happen, but giving workers a chance to correct them can improve acceptance rates. Microworkers allows Employers to request revisions before rejecting a task.

🔹 Instead of outright rejecting a task, provide feedback on what needs to be fixed.
🔹 Workers have 48 hours to revise their work.
🔹 This not only improves worker satisfaction but also increases the efficiency of your campaign.

📌 Problem: Workers make minor mistakes that could be easily corrected, but they get rejected instead of being given a chance to fix the issue.

✔ Solution:

✅ Enable task revision, so workers can correct errors and resubmit within 48 hours.

✅ Clearly explain what needs to be fixed in the revision request.
✅ This reduces disputes and improves worker motivation.

💡 Example scenario:
An Employer running a document proofreading task found that workers sometimes missed one formatting detail. By enabling revisions, the correction rate improved by 70%.

🔹 Extra Tip: Use revisions for fixable errors, but reject submissions that are completely incorrect.

4. Use the ‘Hire Group’ Feature for Trusted Workers

The Hire Group feature allows Employers to create a selected group of workers who have demonstrated high-quality performance in past tasks. By assigning tasks exclusively to these trusted workers, Employers can ensure faster completion, higher accuracy, and fewer rejections.

📌 Problem: New workers may not always meet quality expectations.

✔ Solution:
✅ Create a Hire Group of trusted workers who have previously done well.
✅ Reduce errors by assigning tasks only to experienced workers.

💡 Example scenario:

An Employer running a complex data annotation project found that new workers made frequent mistakes. By creating a Hire Group of top performers, they increased approval rates by 90% and reduced review time significantly.

🔹 Extra Tip: Regularly update your Hire Group by adding high-performing workers and removing inactive ones to maintain quality.

5. Test Your Campaign Before Full Launch

Before launching a large campaign, it’s crucial to test it to identify potential issues. Microworkers provides a Sandbox Account, which allows Employers to simulate and test their campaigns before going live. This helps prevent confusion, errors, and unnecessary rejections.

📌 Problem:
Employers often discover issues with task instructions or requirements after launching a large campaign. This leads to worker confusion, high rejection rates, and wasted time fixing errors.

✔ Solution:
✅ Use a Sandbox Account to test your campaign before going live.
✅ Launch a test campaign to identify common mistakes or unclear instructions.
✅ Refine and adjust task requirements based on your constructive observation before full deployment.

💡 Example scenario:
An Employer running a product categorization task tested his campaign using the Sandbox Account. He discovered that one category label was confusing, revised it, and reduced rejections by 85% after full launch.

🔹 Extra Tip: Always review test campaign before launching a full campaign to avoid unnecessary mistakes and ensure smooth execution.

6. Track Your Rejection Rate and Improve Over Time

Monitoring your rejection rate helps identify recurring issues in your tasks, allowing you to refine instructions and improve worker performance. High rejection rates often indicate unclear requirements, overly strict evaluation criteria, or task complexity. By analyzing rejection patterns, Employers can make necessary adjustments to ensure higher accuracy and smoother task completion.

📌 Problem:
Employers often reject tasks without reviewing why mistakes occur, leading to frustrated workers, unnecessary disputes, and inefficient campaigns.

✔ Solution:
✅ Regularly track your rejection rate and analyze common mistakes in worker submissions.
✅ Determine if errors are due to unclear instructions, strict requirements, or genuine worker mistakes.
✅ Modify task descriptions, examples, or acceptance criteria based on your findings to improve future submissions.

💡 Example:
An Employer running a scientific image analysis task noticed a 30% rejection rate because workers missed metadata details. After clarifying the instructions and adding an example of correct metadata, the rejection rate dropped to 10%, resulting in faster approvals and better worker satisfaction.

🔹 Extra Tip: Make it a habit to review rejection reasons after each campaign. Small instruction updates can lead to significant improvements in task accuracy and efficiency.

By applying these strategies, Employers on Microworkers can significantly reduce task rejections, improve efficiency, and build a strong reputation among workers.

📌 Key Takeaways:
✔ Write clear, step-by-step instructions with examples

✔ Use Qualification Tasks to ensure skilled workers.

✔ Enable revisions instead of rejections where possible.

✔ Create Hire Groups to maintain high quality.

✔ Track rejection rates and refine campaigns over time.

Remember, a well-structured campaign benefits both you, the Employer, and the Workers—it saves you time, ensures accurate results, and encourages top performers to return for future tasks.
