I'm guessing from your posts here that you're either very naive and/or too young to have been in a hiring role.

Yes, it does indeed work both ways. Just because you don't understand this doesn't make you in any way correct.

I'm not really sure what your second paragraph means. Are you saying you job hunt while at work? That's not a professional thing to be doing. In any case, writing a cover letter is very easy, so being unable to do that probably means you need to work on your communication skills. Heck, with the amount of posts you've stuck onto HN today alone, you could have knocked up a short cover letter that would suit 90% of technical job applications, so this can't be a time problem for you.
