Don't Go to Work Unless it's Fun Day is observed on April 03, 2023. If it's going to be fun at work on this day, get up and go for it. Otherwise, better stay at home or do whatever you wish to do. However, please be aware: as you could lose your job, the idea of not going to work unless the day is going to be fun could be very risky without asking your boss, so another way to celebrate that day would be to just have fun and enjoy your work. Employers also could use this day to show their employees that work indeed can be fun: just be creative.
