I was laid off last December while on short term disability. Several things that have been said have bearing here and several things to keep in mind.
1) I was out on STD, but technically not yet official. Actually did not become official and retroactive until the end of December. Either way I would have been at home and not out in the field.
2) My manager had been previously notified that I was on STD, so he did not contact me, I contacted him and was pretty sure what he was going to say about my "position" since I had a "1" in sales for CY 2008 (1st time in 12 years with Novartis).
3) Packet was already in the mail and arrived the following Monday because the company did not yet know I was on STD either officially or unofficially.
4) STD would not really protect you as as soon as you come off you will be offically notified that you are part of the layoff. Remember, the decision was made to eliminate your position before you went on STD.
5) If your condition is serious enough to last 6 months and then be converted to LTD, that is a consideration. Under the "rules" of the last layoff, STD payments would have stopped as of the day the WARN ACT 60 day period expired. If not on STD, you get your severence and all other applicable benefits. If still disabled you are basically on STD without payment and payments would not start again until you run thru your full allocation of STD days; at that point your LTD kicks in. If you had the company provided LTD where you did not contribute, the payment is 50% of salary and bonus, but if you supplemented that thru a payroll deduction, it would be at 67% of salary and bonus. Keep in mind that maternity STD would rarely, rarely ever roll into LTD (LTD is expected to last 2 years or longer).
6) I wasn't sure about recovery in my case. I put together an Excel spreadsheet to see when LTD payments would "catch up" to severence payments plus other layoff benefits and it would not catch up until something like March or April of 2012, assuming that I did not find other work.
In my case my doctor felt that my condition was getting better and he would not support LTD anyway. I let the STD run for 6 weeks and then fell into the pool with the other 1399 that were laid off.
Now working again and in total remission from my cancer.
