I'm actually onboarding at a remote position right now where the people I work with are clearly used to everything happening in an office. It's Thursday, I started Monday, and I have spent a grand total of maybe 3 hours speaking to my teammates or direct manager.
I've been dumped with a ton of documentation and stuff to read, but I feel extremely isolated. No one on my team has reached out to welcome me or make themselves available for questions or anything.
If this is what some people are experiencing in the remote world I don't blame them for wanting to go back to the office. It certainly is not how I've experienced remote work in the past so far.
