- eBay managers often use "Leave of Absence" to recharge themselves or find new employment. It is actually ideal because they can always return to eBay.
- Meg has been exercising options regularly all year and certainly could afford to defer her compensation for an extended period of time.
- John Donahoe has been hitting the PR trail heavy over the last month and looks to be in line to take over while Meg is away, either as interim CEO or officially as the new boss. If he's successful, with the changes he's making, Meg can leave knowing that the company is in good hands. If he fails then she can come back (assuming Romney loses) and save the company.
- She is very involved in Mitt Romney's campaign and I would say if he wins, she will be offered a cabinet position (Commerce Secretary) and who would turn that down. By not leaving eBay officially she hedges her bets. If Romney does not get the nomination then she can come back to eBay. By taking a Leave of Absence she can work on his campaign indefinitely.
I'm sure you can come up with other reasons this idea makes sense, I've just listed a few. If I was a betting man I would say that Meg will announce here Leave of Absence in January and hit the campaign trail for her good buddy Mitt.
So, I guess if anything really interesting comes up between now and the new year I'll post about it.
Just my 5 cents.
