> You should also assume all of your traffic while at the office
I fell out with my manager at FANG and she got back at me with the lowest rating possible for the year-end review. I chose to get my concerns across to HR about how this was unfair and challenged them to validate her critical feedback with peer engs. Didn't happen.
Instead what followed was, I was investigated for violation of company rules such as putting company laptop to personal use, violating social media policy, holding on to company documents for more time than company's policy permits... among a lot of such trivial other things (I was astonished at the intelligence they had built up, I guess, by using responses to internal surveys, predicting probability to have done something via browsing patterns, keeping tabs on laptop disk usage etc).
Once they had built "a case" they would go on to engage legal and terminate my employment with what I presume now qualifies as "just cause" and avoid having to pay any severance.
Has worked wonders for them, this tactic. I have since heared that a few other employees have been handled in a similar manner and that I was not the only one.
