Kind of. In 2010 the government started automatically enrolling new employees in the TSP with a 3% deduction allocated to the G Fund. Current participants had no changes made to their funds and nothing stops an employe from changing the allocation or dropping out completely.
Lots of private companies do the same thing, automatically enrolling employees into a stable value fund of their 401k, as 401k rules become very restrictive for high earners if not enough employees participate.
“...In 2010 the government started automatically enrolling new employees....”
No. Not new employees getting started. That’s no big deal and some private firms do the same thing as you alluded. They supposedly did this to employees that have been there a long time and have built up a tidy little amount. Here recently, they supposedly just went in and moved all their money out of the C Funds, I Funds, etc. and moved it over to the G Fund!!! They also changed their future contribution allocations from whatever they had previously elected over to the G Fund only. They moved their money and allocation choices without even notifying them.
