Check your states rules on WARN ACT: Some states now requires a 90-day notice before a mass layoff or the closure of a facility, a significant increase from the previous 60-day notice. The state's law, known as the (your state) WARN Act, now applies if 50 or more employees statewide are laid off and includes part-time workers in the count. If the 90-day notice is not provided, employers must pay an additional four weeks of severance pay in addition to the mandatory one week of severance per year of service.
Employer "establishment": The definition of an "establishment" has been expanded to include all facilities in (your state), and layoffs at different locations may need to be aggregated to meet the 50-employee threshold. This includes remote employees who report to a (your state) location.
Severance pay: In addition to the 90-day notice, employers must provide severance pay of at least one week for every year of service. If the 90-day notice is not given, an extra four weeks of severance pay must be provided.
