Some days it’s tough to produce good quality work. When one is exhausted the quality of work will suffer. It is a pity, the societies we have built do not cater for days where individuals, for whatever reason, are not at their best. Days where everyone is better off if you stayed home.
A trusted employee may enjoy a boss who permits such habits, provided they do not affect overall performance, but as with anything pleasant, there will be those who seek to take advantage and in so doing ruin it for everyone else.
How does the saying go? “This is why we can’t have nice things.”
