This environment is toxic. Unless you are in the inner circle and well liked you will forever have problems. Do not complain to HR you will wait 6 months for reply that reads. "No issues found" that does not even come from the HR person that was or is handing your concerns. As for calling the ethics hotline yet another joke... I was once called into a meeting and told turn off your phone and do not tape this conversation. In a call to ethics that was discussed so much for safe guarding the employees.
management Favortism, unfair hiring/firing practices, did I mention management
