2. Being too vague about your symptoms

Why it’s problematic: Being too vague can raise suspicions and make your boss wonder if you’re telling the truth.

How to fix: Be honest and clear about your symptoms, but avoid going into too much detail. For example, “I’m not feeling well and have a fever” is better than “I’m just really tired”.

3. Not following company protocol

Why it’s problematic: Not following company protocol can lead to confusion and make it harder for your request to be approved.

How to fix: Check your employee handbook or ask HR to make sure you’re following the proper procedures for requesting a sick leave.

How to fix: Be responsive and cooperative, and answer any questions your boss may have in a timely manner.

7. Taking a sick leave without a valid reason

Why it’s problematic: Taking a sick leave without a valid reason can damage your reputation and relationships with your boss and colleagues.

How to fix: Only take a sick leave when you’re genuinely unwell, and be honest with your boss if you need a mental health day or a personal day.

8. Not showing appreciation for your boss’s understanding

Why it’s problematic: Not showing appreciation can make your boss feel undervalued and less likely to be understanding in the future.

How to fix: Express gratitude and appreciation for your boss’s understanding, and acknowledge their support.
