I have had jobs where it feels like this and it makes time off more stressful. We tend to put pressure on ourselves and feel like we have to do it all. This comic reminds me to share my knowledge, offer training and prepare good documentation so that when I am away, things still can run smoothly. Some might feel like doing this will be detrimental to their job security and diminish their value in the organization but when things run smoothly and we work together, we're all winning.
