I work for a company that recently decided to force its workers to save for retirement. They auto signed everyone up for a 401(k) to which they don't contribute - and for which we are responsible for fees. To opt out, you have to log on to a very unfriendly Fidelity website and screw around for awhile before you figure out how to opt out of a very stupid plan.
Call a labor lawyer, if they don't have a signature from you, I'd take this all the way from suing them in court to a supreme court ruling if I had to.
Then I would sue them again for firing me, over the huge stink I would make over such a violation.
They don't contribute to it, nor do they subsidize the fees.
Right, but the benefit is tax-deferred savings (or post-tax with no future taxation, if Roth). In some cases it can be better to save in a taxable account, but it's unclear whether this is one of those cases.
