Frequently Asked Questions

What is the '100-80-100' Rule?

It is the gold standard for the modern 4-day work week movement. It means the employee retains 100% of their salary, works 80% of the time (32 hours instead of 40), and commits to maintaining 100% of their previous productivity/output. This represents a massive, mathematical 25% increase in your True Hourly Wage.

What is a Pro-Rated Salary contraction?

If your employer refuses the 100-80-100 model, they may offer a pro-rated contract. If you drop from 5 days to 4 days (a 20% reduction in time), they will drop your salary by 20%. While your hourly rate stays exactly the same, your overall gross income and liquid cash flow shrink. You must run this through a budget planner to ensure you can survive the cut.

Is a Compressed Schedule (4x10) the same as a 4-Day Work Week?

No. A compressed schedule means you still work 40 hours, but you cram them into four 10-hour days. Your total hours and hourly rate do not change. A true 4-day work week is a reduction in total hours (e.g., 32 hours) designed to eliminate busywork and increase per-hour focus.

Why is 'Time Arbitrage' important?

Time Arbitrage is the concept of recovering uncompensated time to deploy into higher-yield activities. If you recover 416 hours a year by dropping to a 4-day week, and you deploy those 416 hours into a scalable side hustle or freelance business, your total annualized income will frequently eclipse your old 5-day salary.
