Yes there are pros and cons to every situation. You are right that it’s harder for new employees to learn. It takes more time. But the advantages of working from home are amazing and so much worth it anyway.
The entire idea of everyone leaving their apartments every morning, when they have everything they need to work at home, contributing to environment destruction, morning stress to get to work, an entire workday of hours lost in traffic every week etc… What are we doing? It’s madness.
Most people used to spend 10 hours every week traveling to work! That’s 40 hours per month - an entire work week just gone sitting in traffic every month! What if you exercise 40 hours per month instead. You would be in stellar shape.
We are supposed to be living life, don’t waste it.
