Don’t overthinking this. If you can’t drop it, and you know the CPO won’t help, call in sick. Get the doctors note from MinuteClinic in advance. Don’t non-rev on your own airline or buy zeds through the company portal. Rev is fine, but best to avoid being seen on company. CASS pings are not archived and KCM is privately held. When you notify them of your marriage for benefits, benefits and travel depts are not going to compare that to your attendance. Companies don’t have time for this level of investigation. Your greatest chances of getting caught is via social media.
