“Military duty” isn’t the same as a job gotten on the “open market.” A servicemember stands 24-hour duty routinely and never gets paid overtime. They are sometimes called to show up at their duty station on the spur of the moment, in uniform for impromptu exercises. Their seabag (Navy and Marines) must always be fully packed and ready to take with them at any time. US labor laws do not apply to military personnel. If they are sick, they must report to work, anyway (even if they have to be brought in), unless they are in the hospital. They will be taken care of at work if they are really sick. As I stated, when one is an active-duty military member, their azz really does not belong to them.
