> It also helps me keep my job during layoffs because I can assure you the managers have noticed.

I can assure you that when they are laying off to cut costs, which is most of the time, what they notice is A) the old/expensive ones who can be let go without any major disruptions and B) the "expendables" such as contractors or those they have a personal dislike of - the latter usually has not much to do with hard work and a lot more to do with perception. Category A is to meet cost targets while category B can also help with number targets.

If you think your hard work alone will save you, I pray that life spares you that rude shock.
