To narrow the scope of the question, I will isolate the job to a corporate environment in which the job revolves around the provision of business improvement recommendations and strategic advice to the various clients of the business. It is above an entry-level position but not an executive level job.
I am curious to know broadly what might be the common indicators that users have personally observed when it comes to inevitably losing a job. It's clear to me that there are a plethora of hints or indicators that could allude to the possibility of a termination. However, I'd like to narrow it further to subtle cues that could imply an imminent employment termination.
Theoretical and anecdotal responses are both welcomed.
