How do I know if my pay is fair in Illinois?
To determine if your pay is equal or fair for different criminal justice roles in Illinois or Chicago, you can follow these steps:
Research salary data
- Bureau of Labor Statistics (BLS): The BLS provides comprehensive data on salaries for various criminal justice roles. You can look up specific roles and compare their median salaries both statewide and in the Chicago metropolitan area.
- Salary websites: Use websites like Glassdoor, PayScale and Indeed to find salary information for your specific role and location. These sites often include user-reported salaries that can give you an idea of the current market rates.
Check job boards
- Current listings: Look at job postings for similar roles in your area. Compare the advertised salaries with your current pay. This can give you a sense of what employers are currently offering for your position.
Review your union contract
- Union agreements: If you are part of a union, review the union contracts, which typically outline pay scales, raises and other compensation-related benefits. Union representatives can also provide information on whether your pay is in line with negotiated agreements.
Compare with colleagues
- Peer comparison: Discuss salaries with trusted colleagues in similar roles to understand how your pay compares. Be aware that pay can vary based on experience, education and specific responsibilities.
Consider any cost of living adjustments
- Cost of living: Use cost of living calculators to understand how your salary compares when adjusted for the cost of living in different areas. For example, higher salaries in Chicago might be necessary to offset the higher cost of living compared to other parts of Illinois.
Review professional associations reports

Evaluate your total package, not just pay
- Benefits and perks: Consider the total compensation package, including health benefits, retirement plans, overtime, paid time off, bonuses and other perks. Sometimes, benefits can significantly enhance the overall value of your compensation.
Factor in your responsibilities and experience
- Role and experience: Ensure you compare salaries for similar roles with comparable responsibilities and required experience. Specialized roles or those with higher risks may command higher salaries.
Take any final steps
- Negotiate: If you find that your pay is below the median or not competitive, consider negotiating with your employer. Present data and make a case for a raise based on market rates and your performance.
- Professional development: Sometimes increasing your qualifications or taking on additional responsibilities can justify a higher salary.
- File a complaint: The Illinois Department of Labor has an investigation line (1-866-372-4365), or you can file a complaint on their website if you still feel you are being paid unfairly. Any complaint must be filed within one year of the violation occurring.
