So I have been enduring a series of stressful episodes with my uppers at work.
Preface:
A co-worker of mine found a news article online depicting my manager as a felon and claiming that she had embezzled more than $20,000 from the place of business at which she previously managed.
At first, I was in complete disbelief but the description of the woman matched my manager's work history, physical identity, and the previous location in which she lived. Unfortunately, the article also claimed that she is currently out on $15,000 bail.
Now, herein lies the issue, my co-worker (the one who found the article) was fired because she posted a tweet exposing my manager's teenage daughter for a drug addict via screenshot of a text message. When my manager came across this, she demonized my co-worker in the eyes of the owners until they agreed to let her go.
In retaliation, my co-worker typed a letter listing all of her grievances and the unprofessional way in which the store had been run as well as an attachment of a copy of the news article marring my manager's legal history.
My dilemma rests in the fact that because I was friends with my co-worker; my manager is convinced that I am out to undermine her and "sabotage her job" as well. She has interrogated other employees and attempted to force them to admit that I was the one who sent the letter in when the fired co-worker admitted to doing it herself. My manager also freequently cuts my hours and changes my schedule with complete disregard for my pleas to have off. When I turn to the owners, they seem completely fooled by the beliefs of their manager and have black-mailed me by withholding all of my hours until I can admit that I had a hand in uncovering details about my managers indecencies with the law.
Here's why this is so frustrating:
My manager grew up with the owner's and they are from the same home town. They are convinced that I am out to expose their hired felon to corporate headquarters and report all of their misconduct.
My question:
What can I do legally to combat this? Is my only option to resign?
I understand this job is not my main source of income as I am still in high school and am under the wings of my parents but I feel as if a real injustice is in place and I have an opportunity to quell it.
