Standard UK Work Week: 37.5 vs 40 Hours
In the UK, a "9 to 5" job typically includes an unpaid lunch hour (or 30 mins). This means your actual working hours are often 37.5 hours per week, not 40.
This difference matters! A salary of £35,000 on a 37.5-hour contract pays £17.95/hr, whereas on a 40-hour contract it pays only £16.83/hr.
