So I started a new gig earlier in the year which was a significant pay bump from my previous position, but of course the position was only open because the person that held the job before me was let go(due to making too much money after multiple raises). Upper Management & executive leadership told the entire IT staff in a meeting, that they wouldn't be cutting any more tech employees after this. Two months later, they just cut the IT director who's been here for almost two decades and literally replaced him with a new employee one day later, just to cut costs. This environment already seems extremely toxic

After all these changes & upper management basically being dishonest to our faces, I don't feel very comfortable at all in my new position. It's a bit of a difficult spot because I've only been here about 5 months. Should I just ride it out the rest of the year and focus on myself obtaining more certifications or should I go back on the market again?
I'm also starting to realize culture>>>>>>>>>>>>>>>>>money.
