Opinions on April Fool's Day tend to vary pretty wildly. Some love it, thinking of it as a light-hearted day full of silly goofs to spread joy. Others despise it, as it leaves them on edge and unable to trust anyone.
To me, it all depends on the jokes being made. For example, the 'joke' that sets off this story? Terrible. An employee walked into work on April Fool's Day only to be told they were 'fired', so they played along, leaving their boss infuriated.
