According to the District of Columbia’s Accrued Sick and Safe Leave Act, both full- and part-time employees to be paid sick and safe leave for use under certain circumstances.
I'm working as a regular full-time employee for a company, that has the only office in Washington DC.
There is an internal document in the company, that states that
In accordance with the District of Columbia’s Accrued Sick and Safe Leave Act, special full-time exempt, part-time and temporary employees are eligible for up to five (5) days of paid sick leave.
...
Regular full-time employees are not eligible for paid sick days under this policy. Instead, they may take any accrued PTO for any reason, including illness.
Is it legal, or this statement is misinterpretation, and I'm also eligible for paid sick leave?
