Prediction of job is not an easy task. Job or profession plays between a individual and companies, country, world. Basically is not like marriage where only two families or sometimes two people are involved. In job, things are very wider. Which makes its prediction little difficult than marriage, childbirth, health etc. Though involvement of desh, kaal, patra is in everything but job is having more.
I will not complicate things, and try to give strong and very simple techniques of job prediction. I advise seeker to learn and use more than one or two dasha system for job predictions, like vimshottari, chara, yogini, and kaal chakra dasha.
For job, artha trikona houses 2, 6 and 10 are very important. 11th house also.
2nd is our resources, 6th is service and 10th is work and actions. 11th house is gains of 10th house, income.
Saturn is karaka of profession, and Mercury and Mars are secondarily important.
So, whenever dasha of planet related to 10th house/lord operates. Person faces events related to job, but this dasha should be of planet promoting 10th house for gain of job and the planets which demoting will give loss of job.
11th house, 2nd house and last 6th house, planet in rajyoga or good with 10th house/lord promotes job.
12th, 3rd, 4th and 5th house/lord demotes 10th house. But here 5th if associated with 11th or 2nd house gives promotion as well. And 12th house can also give job away from home, and 3rd can give self-employment as well.
D-10 chart is very very important. So, check D-10 chart as well. If planet related to 10th, 11th, 2nd and 6th house of D-10 then job gain is seen.
One should not forget 7th house, 7th house also shows, but explaining that will make answer complicated.
Amk is important. So, see Amk in dasha. It should be in 10th, 11th, 2nd, 7th, 6th from dasha lord or sign.
