At least with JC, there was a different tone of LR'ing most of the people at once.
It felt like there was a shift in LR "culture" with the arrival of CR and new EVP team; moving to a Soprano "hit" type subliminal ongoing targeted LR under-the-radar constant mini-purge.
However, or whomever, decided that this shift makes sense; do they care on the effect of organizational health?
People commit to relationships and give the best of themselves when they feel safe. In a scenario of no formal reviews, you have no process of knowing how Cisco really feels about you.
So without reviews, like a bad marriage, you are left to guess on how good of a job you are going in the relationship. Like a bad marriage, the partner will only guess on what to give because the other person might not want a relationship with you this time next week, month or year. Choose the time target; they are in control...but will say "everything is fine", with a smile on their face. Just like "everything is fine" on a Cisco Beat show.
If you are feeling anxious, can't sleep, or just don't feel the same as you did a few years ago...maybe it isn't just you getting older...it's the shift within the place you spend most of your waking hours most of the week.
