After doing some research on this issue, it seems the only change as of 6/1/2016 is that Aetna now administers the plan instead of Cigna....that's it!!
The plan itself hasn't changed, contrary to the scare tactics, the policy that the company can hire a replacement employee after 26 weeks of STD has been the policy for as long as I can remember!! Most of you probably don't realize that the law says companies can replace employees after only 12 weeks of disability!! Again, in my 21.5 years I only know of one driver who didn't retain their position after returning from disability but that was due to the 2009 layoffs, had he not been on disability he still wouldn't have made the cut due to his lack of seniority....but I am at a hub where absences are more easily abosorbed than they would be at smaller centers.
Senority is still retained for up to 18 months (6 STD, 12 LTD) just like it's been for as long as I can remember!!
