Survey: Dirty shared office spaces are pushing workers to consider quitting

Invisible Sun Technology’s Fall 2026 Back-to-the-Office Index found cleanliness concerns are hurting how employees view their offices and employers. The survey of 646 U.S. workers suggests building owners and landlords may face higher pressure to improve cleaning compliance as offices fill up this fall.

Why it matters: - Cleanliness is shaping whether workers want to return to the office, how they view employers and whether they consider leaving. - The findings matter for building owners, landlords and janitorial teams because office hygiene is tied to tenant retention, complaints and operating costs. - Invisible Sun said its new calculator is aimed at showing the financial case for improving cleaning compliance.

What happened: - Invisible Sun Technology released the Invisible Sun Fall 2026 Back-to-the-Office Index on Oct. 13, 2026. - The survey found one in three office workers see dirty shared spaces as a problem. - 58.3% of office workers said the office environment negatively affects their desire to go to the office. - 48.3% said the office environment hurts their perception of their employer. - 40.7% said the office environment prompts them to consider leaving their employer. - The survey polled 646 U.S. workers in August and September 2026. - The margin of error was plus or minus 5% at a 95% confidence level. - Invisible Sun Technology is headquartered in Doylestown, Pennsylvania.

The details: - John Kunzier, CEO of Invisible Sun Technology, said more workers are back in the office as fall begins and school is back in session. - Kunzier said many workers did not like what they saw when they returned. - Invisible Sun launched the Invisible Sun Contactless FM Value Calculator in September. - The calculator is designed to help building owners improve cleaning compliance, increase productivity and lower operating costs tied to the third-largest maintenance and operations expense. - Building owners and janitorial companies can enter labor costs, staffing levels, service schedules and compliance rates into the calculator. - The tool estimates potential savings from using Invisible Sun’s proof-of-presence solution. - Invisible Sun says proof-of-presence technology addresses a key post-Covid responsibility: keeping office environments clean. - Research cited from The Association for Cleaning & Facilities Solutions says office buildings with top-quartile cleaning satisfaction can increase tenant retention by up to 25%. - Invisible Sun Technology connects soft FM service delivery with workspace management. - The company says its system helps organizations verify work, respond to actual building usage, improve cleaning quality and simplify hybrid workplace operations through Contactless Facility Management. - More information is available in the company’s announcement.

Between the lines: - The survey suggests workplace cleanliness is no longer just a facilities issue. - The results point to a broader link between visible office conditions and employee loyalty. - Invisible Sun is using those concerns to position its technology as a cost-saving operational tool, not just a cleaning product. - The timing also matters: fall is one of the busiest seasons for offices, which can make hygiene problems more noticeable.

What’s next: - Building owners and janitorial providers may use the calculator to test whether proof-of-presence technology can justify adoption. - Employers facing return-to-office pressure may need to treat cleaning performance as part of retention strategy. - Invisible Sun is likely to keep marketing the calculator as a way to quantify savings and improve compliance.

The bottom line: - The survey frames office cleanliness as a direct business issue, with measurable effects on attendance, employer sentiment and turnover risk.
