It's an interesting time with my chart right now, the angles getting hit by Saturn Uranus.
With Saturn crossing my 4th, I am feeling the pressure to put down roots but what I am seeing/learning is that I've got to make career moves first in order to have this.
What happened for you when Saturn opposed your MC? Any career stuff?
When Tr. Saturn opposed my Scorpio MC/Saturn and conjuncted my Taurus IC/Venus I was obsessively engaged in genealogy, tracing some branches of my family tree back as far as three-digit centuries. A few months later I travelled to explore a few related locations.
When Saturn was transiting my IC in 2010, Uranus was closing in on my MC - interesting different relationship between Saturn and Uranus through time. I started craving a big change in career at that time because of the Uranus influence. (Would Uranus be prompting you to make relationship changes?)
By January 2012 Saturn had helped me maintain the discipline though to acquire my mortgage on a brand new condo. Saturn was still 4th house. Once I had the condo I left a higher paying job for a different one. It turned out in one way to be a big mistake! or at least I question it.
Saturn loves the chart Angles - exalted in Libra - and especially the MC/IC axis.
Transiting Saturn went past my IC recently ( about 7 degrees Aquarius) and over the past several years I have been reinvigorating a 50 year career with new outlets for my guitars.
At the same time some very old dark emotional trauma was recapitulated and freed up which removed some of the perfectionistic obsession that went into my craft and career.
The notion that Saturn is oppressive structure needs some reworking. Saturn is change and governs the Angles which are inflection points for the changes in direction of emotion and energy.
I can't speak for opposition but i can say couple of words about Square transit.
I have this in natal and during my Saturn return in Spring 2020 i have had this in transit as well.
Couple of months later i got an opportunity to start new career and learn new skills, develop and experience whole new field in life. But...
It was nightmare. Abusive environment, murk collective, negativity was felt in the air the moment you enter that office.
The discipline level which was required in that work place was more on abusive side of spectrum than actual professionalism.
Very draining on soul level. Even on good days you just feel it's all temporarily and masked. God save people who get hired to work there.
I had it during my Saturn return. My hours were cut at work. I was struggling financially during that time. I got a job as a caregiver and that set me on the trajectory toward the career I have now. I decided what I wanted to do, went back to school, etc.
