I don't know why your job would they give bad reference but in my work experience I know it happens come to my office for all types of unnecessary reason and untrue reason but all I ends up with they (Employers) didn't want you to go and others ( Employees)having negative input on you when you was there Even though there wasn't any negative thing to say all it take is one to start the conversation and others co-signed to it some could be just coming on board don't even know anything about you 😔💔🙏 #termination
