I have learned to be really careful on this one. I held a job once where a new supervisor came in that didn't like me. (I was fine under the old supervisor.) The new one brought me in one day and told me I needed to resign immediately, and if I refused, he would fire me because the application has a disclaimer on it that you sign saying that everything on the app is true to the best of your knowledge. Well, I had forgotten to write one of my employers
in there. It had been a job I HATED, and it only lasted a couple months, and I forgot about it when filling out the app. So, this supervisor claimed that I broke the law because I didn't divulge that employer on my app. He threatened a lawsuit if I didn't resign immediately. So now, when I fill out an app, if it's in person, I explain that I usually hold more than one position at a time, like in addition to my full time job I usually work contract or temp nursing too and do not include those on the app. I explain these things before signing the application. Online you have to sign, but if I get an interview, I make sure to explain this so that I don't end up "breaking the law" again. That was a horrible experience.
By the way, not only did that supervisor not like me (I didn't much care for him either), 2 weeks after he forced my resignation, the company closed down and they had to pay severences. I was one person who they didn't have to pay I guess.
