I received three weeks' pay after 18 months of service. No other benefits. Hollett's been configuring severance packages for corporations for 30 years.
Most companies use service to determine severance figures.
The older the person and the higher the person is in level, the longer it takes to bridge. Following Hollett's reasoning, assume a package that begins with one week's pay per year of service. For employees over age 40, add an additional week for year of service for a total of two weeks' pay per year of service. For the over-40 employee, that adds up to a total of three weeks' pay per year of service. Garden Variety Averages.
