The first one is correct. The definition of 'sick leave' in wikipedia:
Sick leave(or paid sick days or sick pay) is an employee benefit in the form of paid leave, which workers can use during periods of temporary sickness or to stay home and address their health and safety needs without losing pay or their jobs. In some places of employment it is a workplace policy, and in many jurisdictions it is codified into law. Some policies allow workers paid time off to attend doctor visits or to care for family members.
But I don't think we should use the simple present here, it should be the present perfect tense.
