The company I work for (publicly listed) has granted company-wide access to Copilot, but requires users to complete a pretty extensive (2+ hour) training module before you’re able to use it.
Pretty obvious stuff like, don’t upload sensitive data, validate output etc. I just use it as a glorified search engine usually - validating function syntaxes etc., and also cot rewriting email to be less blunt.
Really comes down to whether companies have; no tech departments to stop employees from using AI, small departments that don’t want to deal with the headache, large departments capable of managing the rollout.
