I’m assuming this is a cash balance plan, the value should never decrease. So that is odd. Need to investigate how it is decreasing.
Also from reading, it sounds like you had the option of the pension or 403b. And you tried to pick both, but you had the option of one or the other. Maybe you made a mistake if that was around 2013 when you’ve said your employer switched you.
It’s worth checking that your employer has been contributing however much you were entitled to under the 403b plan since you were switched over
Perhaps at some point around 2012-2013 you were no longer considered a full time employee / employee at all, and depending upon the plan rules, lost eligibility to the pension, forcing you to switch over. Some plans have boomerang rules (leave your employer then return) that would grandfather you back into the pension, but many did not. If this was around the time you were at pharmacy school, I would recommend you find copies or your pension rules, and read them all in detail. This is where’d you’d find out about eligibility based on FTE or PTE status, boomerang provisions, etc. You may have needed to elect to return to the pension as well.
If you find anything compelling in there that you should still have been eligible, set up a meeting with someone from HR / benefits at your company and discuss options and what they willing to do.
If they don’t budge, which they likely won’t, consider how much they’ve contributed to your 403b, what’s it’s grown to, and if you’d be fine with all of that getting removed. Do the math on how much that would be in your pension (based on the pension rules). If you still want the pension, and they won’t budge, consult a ERISA or employment lawyer
