Neither the California Labor Code nor the federal Fair Labor Standards Act require employers to offer severance agreements to departing employees. Instead, severance agreements are provided by employers to accomplish a specific goal.
Some factors that are often considered include length of employment at the company, your position or rank within the organization, salary, and individual circumstances relating to termination. Some employers adhere to a written contract or employment agreement or policy that was outlined previously.
Ing to the Utah Employment Security Act, ALL severance and accrued vacation payments are attributable to the period of time following the last day worked. Unemployment benefits are denied for that period of time.
Voluntary separation offers on the other hand, are not typically calculated based on years of service, but are rather a multiple of monthly salary (i.e., 5-6 months of salary) to ensure the offer is competitive and attractive regardless of tenure.
