Explanation: Working with the dead is not for the faint hearted but for the brave. Working with corpse can be ominous. Someone who squeals and is usually terrified when watching horror like 6 Fts under, faces of death and so on would find it difficult working with the dead. However, someone that has fancied horror may enjoy the work.
Also, relatives of these dead people come around and it's only a brave staff that would be able to grieve with these ones.
When on night shift, it may want to look really scary but being of a strong mind would go a long way and every other night shift would become a walk over.
