Employees only need a fit note from a doctor after 7 days off work sick and have the right to use their statutory holiday entitlement during their sickness.
Fit notes and proof of sickness
Employees must give their employer a doctor's 'fit note' (formerly 'sick note') if they're off sick for more than 7 days. Hospital doctors or GPs provide them. They can charge a fee if a fit note is asked for before the 7th day.
The fit note will say the employee is either 'not fit for work' or 'may be fit for work'.
If it says the employee 'may be fit for work', employers should discuss any changes that might help the employee return to work (eg different hours or tasks). The employee must be treated as 'not fit for work' if there's no agreement on these changes.
Employers can take a copy of the fit note, the employee should keep the original.
Employers can also ask employees to fill in a form when they return to work to confirm they've been off sick for up to 7 days. This is called 'self-certification'. Employers usually provide their own version of this form.

Sick leave and holiday
Statutory holiday entitlement is built up (accrued) while an employee is off work sick (no matter how long they're off).
Any statutory holiday entitlement that isn't used because of illness can be carried over into the next leave year.
Employees can choose to take holiday instead of sick leave. For example, because they don't qualify for sick pay. Also, if an employee is ill just before or during their leave, they can take it as sick leave and take the missed leave at a later date.
Sick pay instead of holiday pay
When an employee changes their holiday to sick leave they're paid Statutory Sick Pay which will count towards the amount of holiday pay they've received. The exceptions to this rule are:
- they don't qualify for Statutory Sick Pay
- they were off work sick and being paid 'occupational sick pay'
Returning to work
Employers should make changes to an employee's working conditions if they become disabled because of their sickness. These changes are known as 'reasonable adjustments' and could include working shorter hours or adapting equipment employees use at work.
Employees who are off work sick for more than 4 weeks may be considered long-term sick.
As a last resort, employers can dismiss an employee who is long-term sick, but before they can do this employers:
- must consider if an employee can return to work - eg working flexibly or part-time, doing different or less stressful work (with training if necessary)
- must consult with employees about when they could return to work and if their health will improve
An employee can take their case to an employment tribunal if they think they've been unfairly dismissed.
