Check your layoff against the US WARN Act, state mini-WARN laws, and Canadian mass-termination and temporary-layoff rules โ and know what notice and severance you are owed.
You have a saved session. Pick up where you left off?
Employers use softer language for layoffs โ 'restructuring,' 'downsizing,' 'position elimination' โ but for entitlement purposes a layoff without cause is a dismissal. The business reason behind it does not reduce what you are owed; it simply means there is no allegation of misconduct to defend. In Canada, that means you keep your statutory minimum notice and, unless a valid contract clause limits you, common-law reasonable notice, which can run several months to two years of full compensation depending on age, tenure, and role.
In the United States, at-will employment means a layoff generally requires no advance notice or severance under ordinary circumstances. The major exception is the federal WARN Act and its state counterparts, which impose advance-notice duties on larger employers conducting mass layoffs or plant closings. Severance itself remains contractual or policy-based rather than legally mandated in most US layoffs.
The federal Worker Adjustment and Retraining Notification (WARN) Act requires employers with 100 or more employees to give 60 days' advance written notice before a 'plant closing' or 'mass layoff' โ generally defined as affecting 50 or more workers at a single site of employment. If an employer fails to give proper notice, affected employees can recover up to 60 days of back pay and benefits, and local governments may recover penalties. There are limited exceptions, such as unforeseeable business circumstances and faltering companies, but they are narrowly applied.
Many states have their own 'mini-WARN' laws that are stricter than the federal statute. California's WARN Act, for example, applies to employers with 75 or more employees and can be triggered by smaller layoffs; New York requires 90 days' notice and applies at 50 employees; New Jersey, Illinois, and others have their own thresholds and severance requirements. Because federal and state rules can both apply, and thresholds turn on precise employee counts and timeframes, a layoff that looks notice-exempt under federal law may still violate state law.
Canadian employment standards add two layers most employees overlook. First, 'mass termination' rules increase statutory notice when many employees are let go in a short window. In Ontario, terminating 50 or more employees at an establishment within four weeks triggers enhanced notice of 8, 12, or 16 weeks depending on the number affected โ on top of, not instead of, individual entitlements and common-law notice. Other provinces have comparable group-termination provisions.
Second, temporary layoffs are tightly regulated. Unless your contract expressly permits a layoff or it is a well-established practice in your workplace, an employer generally cannot lawfully impose one โ and doing so can amount to constructive dismissal, entitling you to full termination pay. Even where permitted, employment standards cap how long a temporary layoff can last (often around 13 weeks in a 20-week period, with extensions) before it is deemed a termination. If you have been 'temporarily' laid off, it is worth confirming whether the layoff is even authorized.
