I recently applied to a company that is in a similar business space as the place I currently work. The company said that they would need my current employer to sign a release as a contingency upon accepting my offer. My employer would then have the option to be nice and sign the release, or simply say 'no' and possibly terminate me as a result of accepting another offer. My employer did not have me sign a non-compete agreement, so I do no understand why they would need a release.
Is this a standard business practice for companies in order to avoid potential legal complications?
Should I be concerned about the possibility of my employer not signing the release?
