As a general philosophy you should update your resume every 2 weeks. Even if you perform a job that is redundant, you might've encountered a scenario that was beyond your job description or you have data pertaining to be a top performer. You can utilize those experiences on your resume when transitioning to other positions. So if you didn't update it, you might've forgotten about those experience and you lost out. You should also keep your resume open on places like monster.com and stuff, even if you are being inactive about it. After all, you don't want to be stuck in a job you don't like with rude customers and you suffering from paranoia because of job security. Are you sure it's not just paranoia? I think most companies are more reasonable to not fire someone because of bad feedback from one customer. If it were more consistant, I'd worry. I been paranoid about getting fired to the point that I thought it was a sure thing. Hasn't happened.
