The theme whether jobs are or should be alloted to the sixth or to the tenth houses came up in quite another thread in the Horary forum. To clear this matter in abstract, a thread under the same heading as here in "Nativities & General Astrology" is already opened in "Horary & Electional Astrology" and you can find it here:

If you would like to participate in the trying to lighten up this not only for horary very relevant matter, especially by sharing sources and justifications for 'the reasons why', please do this for concentration's sake in the thread on the horary forum. Thanks and please come and share your sources!
