Sometimes, it's cute. "I'd like a day off" out of no-where. Sometimes, it's ridiculous. "I'd like a day off to go day drinking with my buddies" Sometimes, it makes me re-think what and why we do things. This is how we move forward. Case in point, "I'd like a day off. I need a mental health day because someone tried to break into my house last night and I'm freaked out"
Mental health days a total luxury, but if you think about it, there are days we need off because we are going to unproductive regardless. It can be abused, but it can also be useful. Context and Manager discretion matters.
Young People aren't going to save us from the office, but they are going to challenge our assumptions and it's our duty to listen and change the office as needed.
