I'm proactive and tend to ask for forgiveness rather than permission. This has almost always been appreciated by partners. However, some partners expect this behavior but fail to do their part in facilitating it.
Some partners love to send emails to clients without cc'ing me or have calls with clients and never communicate the contents to me. Some partners also decide to change strategies while taking a shit and expect that to be telepathically conveyed to me. I cannot efficiently and accurately manage workflows without information. This ultimately results in me doing something that I shouldn't, which annoys the partner. In response, I will stop being as proactive and then the partner will be annoyed that I'm waiting for instructions. You cannot have it both ways.
