There is a good chance that Disney EEs would NOT qualify for any subsidies.
Subsidies are not ONLY a function of income, but they are also a function of if your employer offers what ACA defines as "affordable" plans, which is classified as 9.5% of the employees HOUSEHOLD (so that includes family members as well) income. If the employer does not offer "affordable" health insurance, then they are in violation of ACA and will be fined. Considering the penalty (2 - 3k PER violation), I am quite sure Disney does.
If your employer does, then the applicant is not eligible for subsidies. At all.
You could get them...if you commit fraud.
At $10 an hour, one of the plans would need to cost more than $1976 annually for EE only coverage AFTER Disney's contribution. The "increase of employee contribution" is that their (Disney's) group health premiums are going up, and Disney has decided not to pay that increase.
The employee can still decline employer insurance if they choose, but they'd be losing out on any employer contribution AND the subsidies.
