I agree, randomly helping out in the first few days is perhaps acceptable but after that, they should be treated as any other employee.

so treat the new employee the same as the employees who have been in the company for a few years and have written a lot of the systems and have internalised the business domain/company setup/system architecture & troubleshooting?

unless a company is rewriting the same 10 input form over & over again, I don't think that will work out great for anyone.
