Google can tell you how much all these professions earn.
I’m a teacher and my salary (fte) is about £42k. Pro rata (21h) my salary is £25k, but I actually work around 30h per week.
Based on a FTE of working 195 days per year, plus 40 days paid holiday (so 235 paid days/year) we earn £178/day, which if we assume the 35 working hours we are paid for is divided equally over 5 working days (7 hours per day) is about £25/hour.
To be paid at £25/hour for the 30h I actually work, my salary should be £39k.
The unions are asking for 10%, which would bring my salary from £25k to £27.5k.
So on paper I’m paid £25/hour, for 21 hours, which is 0.6 of a FTE. I actually work around 30/week, which is 0.85 of a FTE. In real terms, this means I’m paid £18 per hour - my salary of £25k, divided between 0.85 of FTE working days (235 divided by 0.85 is 199 working days per year, which is £125/day, or £17.90 per hour, based on a normal 7 hour working day)
Id say my working hours are on the lower end of normal, others certainly work far more than me.
