unfair/illegal business practices - Express Service Advisor St. Charles Automotive Employee Review

Long Hours, No advancement opportunities,inconsiderate upper management i worked for them and because they didnt like the terms of my two weeks notice "not long enough" not actually two weeks" they decided they wanted to withhold some of my final earnings. And then the manager took the liberty ot texting perspective employers calling me names like "negative nancy" and "debbie downer" i have the proof. i am sure they will reply and say this isnt true. when i get my money i will edit this accordingly
