1. I'm doing my IT resume and want to say that I created a briefing for new employees about safe computing (staying away from bad websites, etc.)  How do I hyphenate it?  This is what I think is correct:

- Developed new employee-safe computing briefing ...

But I used to think this:

- Developed new-employee safe-computing briefing ...

2. For the same IT resume, I want to say that I did a communications campaign that also had the goal of getting stakeholder buy-in.  Again, how do I hyphenate it?  This is what I think is correct:

- Developed communications-and-buy-in campaign ...

(since buy-in is already hyphenated, I used the en-dash for the remaining hyphens, but it still may not be correct)

Any ideas would be greatly appreciated!!! Once I get these two figured out, my resume is finished!!!

Thanks
