Collectively bargained employees in 401(k) plan

[jlea]

I've finished the latest round of amendments in a complex plan and as we're finishing up the conversation, it's mentioned that the plan covers some collectively bargained employees. (I hadn't known from the Plan doc itself as they're just not excluded.) It's my understanding that these employees are a small number compared with the non-CBA employees. My brain hurts and my billable budget with them is running low. What issues should I be thinking about? Any thoughts?

Separate coverage and ADP tests, assuming only one unit.
