Hey Purple, how senior are you? If you have R24 with X-mas off, I assume you are relatively senior. Since they convert in seniority order, if there is at least 30 guys on reserve junior to you, you should be safe from conversion. It's not a clad guarantee, but in the 17 years that I've been here, I've never seen more then 20-25 R lines converted to secondary lines. YMMV. Good Luck!
