What are the regulations regarding the "use it or lose it" vacation policy in Massachusetts?

In Massachusetts, employers are not required by law to provide paid vacation time. However, if an employer does offer vacation time, they must follow their own policies regarding the "use it or lose it" vacation policy. This means that employers can set rules about when vacation time must be used by, and employees may lose any unused vacation time if they do not use it within the specified timeframe. It is important for employees to be aware of their employer's specific policies regarding vacation time to avoid losing any accrued time off.
