Meh. If I were an employer, I'd care much more about the long-term jobs someone had than the one they quit after a week because it was a bad environment. I look at those application forms the same way I look at a resume - it's not a lie of omission to leave off irrelevant short-term jobs. It's simply giving the information that's actually wanted.
From the employer's perspective, I agree with the first half of what you said. A person's performance on a long-term job, and the reasons for why they left that job, are more important than that they got a job somewhere and decided quickly that they didn't like it. As I said earlier, most employers understand the probationary period, during which either party can terminate the employment.
But I continue to disagree with the sentiment you expressed in the second half of your post. It is not the applicant's job to make judgements about what the employer wants on the application, especially if they're using that "judgement" to justify concealing something potentially detrimental. That's not giving the employer what they want; that's giving the employer what you want them to know, and concealing the rest.
And you
cannot omit something that's been asked for and accurately say "it's not a lie of omission". If you were asked for it, and you don't list it, then you omitted it. You concealed it. And when you sign your name at the end of the application, after the statement which usually reads something to the effect of, "By signing this application, I affirm that I have answered all questions truthfully, accurately, and completely to the best of my ability," then you've
lied. It's just that simple.
Now if the employment section asks for all EMS work experience, and you held a non-EMS position for one day, sure you can leave that out. If it asks for your three most recent jobs, and four jobs ago was a short-term job, sure you can leave it out. If it asks for your employment history for the last five years, and you held a short-term job in 2003, sure you can leave that out.
I don't know what other EMS communities are like, but around the Greater Baltimore-Washington Metro Area, it's a small world. At the private companies, most of the employees are volunteers in the surrounding counties. At any given fire station, one volunteer may work for Company X and another may work at Company Y. Stories get around. I was once fired from Company A for a reason that at first glance, without knowing the
whole story, made me look bad. When I applied to Company B, I could have left that job off my application entirely, or I could have put it on but listed some BS reason as to why I was no longer employed there. But my integrity was not sufficiently lacking enough to allow me to do so. In the interview, I explained exactly what happened. And a few months later, one of the supervisors at Company A decided he didn't like working there anymore, left, and got a job at Company B. He wasn't the guy that fired me but he knew the situation, and now he was working at my new job. Stories get around. Stories have ways of following you. You might get lucky once or twice, maybe a hundred times. You might not
ever get caught lying. If you want to take that chance, I can't stop you. Just don't try to justify it to me with "well they didn't want to know about that job anyway" and if you think you can lie
and have integrity, you need to buy a different brand of dictionary.
