Solenta, your argument is terribly flawed. The way you have calculated the figures, it seems a contract pilot only lives for 8 months of the year. Does he not pay bills for the months he’s off? Divide his salary by 12 not 8. His salary should be calculated over a full year as this is the time period he works for the company and also incurs expenses. Many companies don’t allow there pilots to fly in their off time, and his time off is due to him as recuperation time, as deemed by the tax man, and he may not work at home during these times at all, if he does he may not recoup the tax money.
If you want to calculate his pay as tax free don’t negate the 4 months he has to be off in order to get it!
I would have to write a book in response to your thoughts on comparing salaries. It’s awful. With misconceived ideas like yours no wonder there is such a bungle in the payment of pilots.
