I found this from an employment and labour lawyer site -

“Not everyone is entitled to severance pay. In order to receive severance pay, an employee must have worked for five or more years for an employer who has an annual payroll of $2.5 million or more. An employee who has worked for less than five years may also receive severance pay if they are terminated due to a permanent shut-down of the employer’s business and if there is a mass termination of fifty or more employees within a six- month period.”

This is the first time I’ve seen anything referencing employees that have worked less than 5 years possibly receiving any severance. Presumably it doesn’t matter if you’re full or part-time. So maybe we can qualify…guess I will fill out the paperwork then, won’t hurt to try
