Thank you for your question.
Oklahoma, like most states, is an "at will
" employment state. That means that unless you have an employment agreement/union contract that addresses the terms of your employment, an employer is free ot run their company in a manner they deem is best, XXXXX XXXXX as decisions are not based on race, sex, religion, national origin, physical disability, and age, or public policy
(e.g., punishing an employee for reporting an employer who commits a criminal act).
Thus, your employers "no tolerance policy", while not based on any law, doesn't have to be. It may not be the best business practice or the proper way to treat a dedicated employee, but so long as their actions do not run afoul of the law in terms of things like hiring, firing, promotions
, benefits, job assignment, etc. it is legal.
As far as saying that you would be "quitting", well, an employer can't make you quit. They can terminate you, but then it may be easier for you to get unemployment
, whereas an employee who quits is generally deemed ineligible because it is seen as a voluntary separation
