Our company pays the premium for an employee and his family. His family’s premium will no longer be paid by the company. How much of a notice must be given to the employee before the company no longer pays for his family’s coverage?
Employers must give employees at least a 30 day notice prior to recession of a health plan and a 60 day notice for material benefit changes. In other words if a plan is cancelled for any reason it's 30 days, if the plan is going to change benefit-wise it's 60 days. The date of the recession triggers a 60 day special enrollment window for the employee to enroll in a Marketplace health plan, but they can use the prior 30 day notice to shop for plans and get the enrollment in place.
