I'm not sure if this is going to work but:

I have a company schedule on Worksheet 1. It has days, dates, months, jobs etc. in Rows 1-5. There is a variety of formatting present - for example, weekends are filled a certain colour, as are certain jobs.

What I want to do is to have these five or so rows copied onto several other worksheets, including their formats, but make them uneditable.

So if you want to change a job, you can do it on worksheet 1 and can't do it on worksheet 3. But when you change a job on Worksheet 1, it also changes on worksheet 3.

Does that make sense?
