I have been facing some ongoing issues related to excessive workload in my current job, and my attempts to address the issue with both my manager and upper management have not resulted in any progress on the matter. As a result, I am actively searching for a new job.
Recently, my manager called me into a meeting and proceeded to chew me out regarding tasks that weren't being completed in time or things that have gone completely overlooked. I took the opportunity to reiterate to him the type of workload I am dealing with. As a follow up, I put something in writing where I basically asked him to do his job as a manager and prioritize the tasks that he wants done.
This past week, my manager assigned with a project that is completely out of scope of my current work duties and it is on top of my normal work duties, which I am already very far behind in. My manager still has not provided any form of feedback regarding prioritization of work and my attempts to ask him about this have resulted in sarcastic responses. Based on past interactions with him, I feel that he would waste no time in blaming me is something goes wrong either in relation to my existing workload or this new project.
Based on everything I have mentioned, I am seriously considering resigning. My question is this: given the fact that I am currently looking for a job, is my professional reputation at stake if I try to wait things out as opposed to resigning immediately? The company has a no reference policy, so I am unclear as to what can actually follow me once I do leave.
