About six months ago I left my long-time enterprise-y employer for a startup in another city. So we sold our house, packed up the family, bought a new house and moved in.
After 3 months it became obvious I had made a terrible mistake, so we sold the new house, packed up the family again, and bought another new house in the same city we had just left 3 months ago so I could return to my previous employer. They were happy to have me back and I ended up in the same desk and chair I had just vacated 3 months previous.
Only it took awhile. Since I was already in the system as a terminated employee it required manual intervention and code changes to the employee management system to get me added back in. It took about 3 weeks before I could do anything besides go to meetings.
If anything needs disrupting, it’s the employee management systems in use by pretty much all the large enterprise shops. It’s a mess.
