In most cases, employers must continue all benefits until the end of the period of employment. Many jurisdictions include the time equivalent of any lump sum payout such as vacation, sick-time and severance.
Employers should have a policy that determines when the employee can no longer fulfill their part of the employment contract. The period is often as short as 6-months and sometimes extends to age 65.
The policy should be reviewed by legal council, clearly specify the conditions under which each benefit will continue and the conditions under which they will be terminated. Employee life insurance normally contains a waiver of premium provision that will continue coverage while the employee meets a certain criteria. The long-term disability insurance premiums are normally waived for an employee during a claim payment period.
