Do you say "no" when your boss asks you for a favor?
Have you had poor interpersonal relationships with your colleagues?
Do you do less work than your colleagues? Are you disengaged?
Are you combative when issues arise and do you fail to take ownership of them?
Are you sight-unseen? Unreliable? Do you make excuses?
Are you the last person your boss thinks of when there's an important project that needs new team members? Do colleagues not accept your linkedin invitations?
Does any of this sound like you? If so, the fact that you were delusional enough to think that others will be "next" without thinking about what little value you are to the corporation should tell you that YOU are next.
