Recently spotted on a web page of an HR department:
A medical certificate from a registered medical practitioner/registered Chinese medicine practitioner/registered dentist specifying the period of sick leave as well as the nature of sickness or injury is required to support a sick leave application. As a concession, sick leave not exceeding two days may be granted without the requirement of medical certificate. The Head of Department has the discretion to withhold the granting of sick leave not supported by medical certificate. Sick leave more than two days may be granted only on receipt of a proper medical certificate.
If you weren’t already sick, your head would be spinning after reading this.
This paragraph, comprising 89 words, averages at 22.7 words a sentence. This gives it a Flesch reading ease of 29.4 (upper advanced): more difficult to understand than the Harvard Law Review (which scores in the low 30s)!

Flesch Reading Ease
What’s wrong with it?
1. A medical certificate from a registered medical practitioner/registered Chinese medicine practitioner/registered dentist specifying the period of sick leave as well as the nature of sickness or injury is required to support a sick leave application.
Here, 27 of the 35 words specify the subject of the sentence. Many readers will have given up before the end. The writer has made no attempt to relate this information to the reader.
2. As a concession, sick leave not exceeding two days may be granted without the requirement of medical certificate.
This information comes too late. Our colleague read this after submitting a medical certificate: it completely failed to deliver the message.
3. The Head of Department has the discretion to withhold the granting of sick leave not supported by medical certificate. Sick leave more than two days may be granted only on receipt of a proper medical certificate.
The tone is unnecessarily distant, authoritarian and intimidating, especially considering that it is addressed to someone who has recently been sick. It fulfills the vanity of the writer, not the needs of the reader.
Despite its complexity, it is nevertheless grammatically inaccurate. If it were plain English, we feel it would be more successful. How about:
Please read these notes before you apply for sick leave:
If your sick leave is two days or less, you do not need to provide a medical certificate.
If your sick leave is more than two days, you must provide a proper medical certificate from a registered medical practitioner, Chinese medicine practitioner or dentist specifying:
- the period of sick leave
- the nature of sickness or injury.
The Head of Department has the discretion not to grant sick leave if your application is not supported by a medical certificate.
