Statutory Sick Pay (SSP) is a payment made to employees in the United Kingdom who are off work due to sickness for longer than three consecutive workdays but less than 28 weeks.

However, there are certain categories of employees who are not eligible for SSP, including those who are paid less than the national insurance lower earnings limit, new employees who have not done any work under a contract of employment, employees in receipt of Maternity Allowance or Statutory Maternity Pay (SMP), employees recently in receipt of Social Security Benefits (within the last 57 days), and prisoners.
