How do I get over co workers backstabbing

[Flowerpowersss]

Thw weeks leading up to my sudden departure I had highlighted major issues within the department.

i stuck up for my co workers well being and made suggestions on improvements, they told me no one else has complained and I seemed to be the only one who had issues ( I knew this was a lie, as I know people before me had come foward) .

Because I was new I was on probation so they fired me in the end and the reason they got rid of me was ridiculous... if I had been there longer I would have taken them for unfair dismissal.

I honestly don't care I lost this job as I went straight into better less stressful one.
What I can't get over is the people I stuck up for were nice to my face but had been backstabbing me to the supervisors ... I felt like I was still in high school.

I know co workers are not my friends but when I was trying to help everyone's well being and improve things its like a slap in the face .

I wasn't the first to go from this company and I won't be the last , I herd others who have highlighted issues were fired too and obviously the brown nosers stay .

Why can't I get over the betrayal?

OP it sounds like you had a lucky escape! I’d frame it as that in your mind.

Perhaps they just need the job so much that they will do anything not to rock the boat. If they have been there a long time they may have just got used to it (boiling frog syndrome). I agree that it's disappointing that they were slagging you off, especially if the comments were unsolicited, but I wouldn't take it personally. Whistleblowing is always a courageous but risky activity and most people would rather stay under the radar.
