Employees who work at tiny companies can sue for sex discrimination, the Massachusetts high court recently ruled. In the past, it was widely believed that a company couldn’t be sued for sex discrimination if it had fewer than six employees. That’s because the state sex discrimination law says that it only applies to companies with six or more workers. But the court said that an employee at a tiny company could sue under another law – the Massachusetts Equal Rights Act. This is an important decision because almost 60% of Massachusetts businesses have five or fewer employees.  The employee in this case claimed that when she told her boss she was pregnant, the boss became upset and demanded she take an unpaid leave of absence.
