Some jobs are tough to quit

Military service provides obligations you don't see in civilian life. You have less say on where you live. Habitual lateness can result in loss of pay and rank, instead of silent resignation from your boss. And then there's also the matter about whether you're free to quit.

Here is the story of a Nigerian doctor who had to sue the Air Force to let him resign. His superiors argued they did not have to accept the resignation, and labeled him a deserter. Luckily for him, a judge found the law requiring approval to resign in situations like his unconstitutional, allowing the good doctor the freedom to choose how to earns his living.
