Have you worked in a factory floor?
I have, during my younger days, during school holidays. For about 6 months.
Almost every couple of weeks there will be some reason or other for me to go to the office (which was basically in the factory itself), to interact with HR or some other staff.
All I had to do was just walk in, look for the appropriate person, speak to them / sign whatever, and am back on the factory floor in 5 minutes.
If I was expected to make a an appointment, and then try to use an assigned terminal at the appointed time to communicate with the appropriate office staff, it may end up wasting more time. Especially if there are internet or computing problems at either end. Oh, assume there will be problems with signing stuff as well. And as I recall last time, factory floor staff do not generally get official email IDs, etc assigned. So if you want to do digital signatures with your official ID, expect more infrastructure setup to support basically everyone.
Of course things may have changed in the pass few decades. But I do remember my first "real job".
