SC, ok an adjustment, but besides very large companies and even so, this adjustment is not widespread. agree it is not the best but at least this one is cast in concrete. can be improved..
Enveloppes for per diem... EMirates for example has enveloppes with local money distributed to the crew.
Per diems....long story. Bottom line they are here and taxable, but do not count towards any pension
or unemployement inurance
or loss of licence
therefore they are not salary...
