Can I leave my employer subsidized plan?

I believe I found part of the answer to my own question:
"Workers who already have health insurance through an employer can use the Health Insurance Exchanges. However, they may not be eligible for premium tax credits or cost-sharing reductions, unless their employer-based coverage is inadequate or unaffordable."
The part that is not answered is this....if my employer plan is unaffordable because I don't wish to participate in the ( time consuming, big brotherish, arm twisting ) wellness plan, will it make me ineligible? I doubt anyone really knows at this point, it's frustrating that we won't know anything until it's happening.

If your job-based coverage is less than 9.5% of your annual income, it is considered affordable and you would not qualify for the premium tax credit or cost-sharing from the Marketplace. However, if your job-based plan costs more than that or does not cover essential benefits, then you may enroll in the Marketplace.
