Would being convicted of domestic violence crimes make you unemployable in specific industries?
According to this web page, https://www.criminalwatchdog.com/faq/do-misdemeanors-show-on-background-checks, misdemeanors stay on your criminal record for life and they can show up when employers run background checks, depending on how thorough the background check is. The web page has additional information you might want to read.
The definition of domestic violence, according to http://ncadv.org/learn-more/what-is-domestic-violence, is the willful intimidation, physical assault, battery, sexual assault, and/or other abusive behavior as part of a systematic pattern of power and control perpetrated by one intimate partner against another.
In general an employer would avoid hiring someone who has been convicted of domestic violence crimes. There are strong links between domestic violence and workplace violence, and so an employer would assume a lot of risk and potential liability hiring someone who has been convinced of domestic violence crimes. For more information:
Imagine if something happens at work and the victim discovers that the company knowingly put them at risk by hiring someone who had already been convicted of the same crime. This would likely qualify as corporate negligence.
The industries you specifically listed are all high profile, meaning that workplace violence related problems could potentially have a much bigger impact on the image or reputation of the business. These industries are more lucrative, so the amount of money involved in a lawsuit could be much higher. These are professional industries where there is greater importance placed on interpersonal skills and the ability to work well with others. Finally, these are industries where you might end up working with information that is considered sensitive, confidential, proprietary, or even classified, which means that background checks are going to be much more thorough.
To give you an idea of the sensitivity, I work in a similar industry and failed a background check because I didn't realize my drivers license had expired. It caused a lot of problems and was super embarrassing, but luckily I was able to get it worked out and I passed when they ran the background check a second time.
I hope this helps...
