"Most workers in Massachusetts have the right to earn and use up to 40 hours of job-protected sick time per year to take care of themselves and certain family members."
"Employers may cap the amount of earned sick time hours accrued at 40 hours, regardless of the additional hours worked by an employee. Once an employee possesses a bank of 40 hours of unused earned sick time, the employer may opt to delay further accrual until the employee draws down the bank of earned sick time
to below 40 hours."
Or talk to your boss or the company's general counsel. Lawyers are generally pretty good at researching and explaining legal requirements and are definitely a better source than Reddit. There are usually FAQ and calculators available through the AG's office too.
