I'm newly supporting a department, as the previous person left, and also the person he liaises with also quit the same month. A file that gives me data on millions in monthly accruals, sent by a third party, was not received. This file was sent and addressed to “[SVP and Team”], so I sent the SVP an email explaining that we did not receive a file, that we need ASAP, and to please work with the 3rd party vendor to ensure it gets delivered.
Rather than talking to me, the SVP complained to my boss's boss, that it was “inappropriate” to ask for her to do things, that she no longer wants to work with me, and that she will “ignore” my email. The boss's boss asked me to never communicate with her going forward, and to run anything i need her on by him or my boss.
We still have no file with the data I need, but at least I no longer need to directly interact with the Coworker from Hell!
