The 45 day policy is not set in stone. It CAN be extended at a managers discretion, up to 90 days, I believe. When I had my surgery, I was home for 45 days, returned on TRW the 46th day, returned to full duty on the 60th day.....on the same route. TRW does extend your 'time out', as long as your doctor allows it.
Depending on the station, he may need to break up the week, if no full weeks are available. Either that or take a 'crappy' week.
No. I tried getting back onto FO while I had a 40lb limit. 2 years on my FO route, I have never had a package heavier than 10-15 lbs. But, they would not let me no matter what I said or did. You are not allowed back on the road unless you are FULLY released with NO restrictions. It's for your safety and legal reasons. Thin about what would happen if something happened to you or someone else if you had limited mobility.
I read the policy closely. If you are being paid from another source, WC, disability etc, you do NOT have to use your personal and floaters. Since WC and disability doesn't pay you for the first 5 days, you do have to use your sick days. I only had 3 sick days when I went out. The first 3 days were paid as sick days, the next 2 were unpaid (though I did have the option of using my PD or floaters), then disability kicked in.
