IBM

A big and consolidated company, you kinda feel "safe" working for IBM.

Big and consolidated companies, you constantly feel like an "expendable asset". It doesn't matter how important you are; the company will make it clear that you can be easily replaced.

Besides that, at least in Brazil, "manager" is a figurative position with no importance, where usually people lacking competence sit and care only for other incompetent people and brown-nosers.

IBM has this "yearly formal evaluation process" called PBC (personal business commitment) where you are graded from 4 (worst, you are probably gonna be fired) to 1 (top performer). This is subjective as hell; basically, your manager will grade you whatever they want, based on how much they like you. The problem is this rating dictates your opportunities inside the company. For example, if you are not rated 2+, you are not eligible for salary raises, certain training, or opportunities.

Basically, if your manager doesn't like you, they stall your life and career for a whole year.

Start recognizing those who can really make the difference to your department, instead of those who are apple-polishing and doing "extra work" while slacking on the core activity.
