it looks like the "on-sites" are only relevant in the first weeks when someone is hired. If an employee has learned to work consistently remotely, what's the point of having the burden of flying in every few months.
The point is for companies that want their employees to grow and invent, not just be consistent in a narrowly scoped role
Why does this involve the office? It's just my experience, RL meetings are useful for 'breaking the ice' with colleagues, but otherwise remote collaboration = in office collab. This excludes all meta-issues and politics
And how is that not doable remotely? "Learning new technology" can be done at home (or whenever the employee decides) and deployment will happen in a remote server or in the cloud. So, again, how this full remote prevents grow and invent for employees?
