Hi,
The cure for formulas (or code?) that used to work and don't any more should be looked for in those formulas (or the code) or in the system changes made since inauguration. Basically, whatever system of linking you have, has worked once and should still work.
With regard to "real time" you may like to review your requirements:-
If an Employee copy is open you will have great difficulty updating it without the help of the user who is looking at it. If the Employee copy isn't open, why should you want to update it? So, "real time" means that the copy is updated when it is opened. However, if you are thinking of revampingyour system, you may like to look at the possibilities offered by file Sharing. All the problems that come with having linked copies disappear if there are no copies to update, and I'm sure there must be ways to restrict access to read-only on a shared workbook.
Have a great day!
Have a great day!

I do this for "honour and country" - much less of the latter, actually.
If I helped you, award points, plenty of them.
If I bored you, deduct points for being too long-winded. (I know, :lol)
