As i said earlier indeed you will have job change not only job change but also many other changes too , so be ready fro that .
as per raasi 10th lord in 12 house of change and termination of job . now saturn has entered into 12th , we call it as sade satti 7 1/2 yr sani . it brings many changes and many expenditures . so accept it . it will do good in the end .
your saturn dasa ends in 2022 after that mercury dasa starts , it gives many travels and changes in ur life . mercury lord of 9th and 12th gives spiritual related travels , plan your investment well , take care of ur children health . your brother in law health suffers to uttermost . savings gets drained , there will be much expenditure thAN savings , careful with fake religious gurus they tries to cheat you . keyword for mercury dasa is religion/travel and expenditure . only these things will happen .
job change ( in my view its end of your career ) happens in 2022 after may .
your next mercury dasa is not connected to ur 10 th house any way , so this sat dasa is ur last prof life after that you may end up as home maker ...
