Here's what I know from having worked in a toxic environment
Toxic environments are born from power corrupt seniors who thrive on making those under them feel worthless and unimportant. I tried so hard whilst working at my previous workplace. I was there as an intern but I tried my best to work as though I was an employee, all to no avail.
I became a shadow of myself and was left with absolutely no confidence. I questioned everything, my education amounted to nothing. I dreaded everyday that I had to show up to work. In all honesty I blamed myself. I told myself I was inadequate and immature.
To cut this entire post short, to anyone that might be experiencing a toxic environment, I want you to know that it is not worth it. There are better workplaces out there that value their staff and the input their staff put in. Do not doubt yourself nor you abilities. You did not work hard to be a professional in what you do only to be disrespected. You deserve better and you will find a better workplace. I may be unemployed at the moment but I am glad I am having time to reflect on the kind of workplace I know I deserve. In my situation, I'd be tempted to accept anything as long as its a job, but that would be a mistake.
Hope this helps someone,
