Should cell phones be left at home when coming to work? Why or why not?

Should cell phones be unauthorized to bring in to work? Why or why not? Depends on the work location. SCIF or CPA? Don't care where you keep it, just not at work. Otherwise, as long as it doesn't interfere with official duties, I don't have a problem with it.

Should everyone be required to stay in barracks during the work week? Why or why not? Are they on restriction for Art15, standby or recall? Otherwise no.

Hmm, this is an interesting topic.

I can see valid reasons for both sides of both of your questions:

1. Should cell phones be unauthorized to bring to work?
Yes: Not having a cell phone at work prevents massive amounts of distraction and would most likely increase the attentiveness of workers, management, and senior leadership in meetings, briefs, and in actually conducting work.
No: Studies have shown that allowing workers to use facebook, gmail, etc at work actually improves their productivity during the time they are working. The caveat to that is that the amount of increase does not directly correlate to the amount of time spent off the job checking these things. That means a small amount of time on social media or on "fun sites" is good, but anything more is a drag. Additionally at least in my job my cell phone is used at work primarily as a means for people at work to contact me. I rarely sit in my office, so without it, I am unreachable. And finally, it would be horrible to try to enforce. People would flat out hate you for it. Ideally we would just have secure work spaces that we couldn't have phones in for security reasons. "Sorry I'd let you play candy crush but you know, security, gotta leave the phone outside."
Bottom Line: I think it's unrealistic to prevent them, but in important meetings and actually on the job (physically working) they need to be un-utilized unless something comes up.

2. Should everyone be required to stay in the barracks during the work week?
Yes: This way we could easily recall people if needed after hours. We could also count on them to be on time for work, not have long drives (contributing to lack of sleep), and have less of a chance of having an accident while off duty.
No: Realistically everything I put in the yes category as a positive already doesn't happen with those who do live in the barracks. So what do we expect to gain? We would also lose just about every married service member if they were only ever allowed to see their spouses and children on the weekends. Sure the all understand there will be time away, but when at home (not deployed) and during the normal work week? Not doable.
Bottom Line: Just about no realistic benefit to this and a HUGE negative.

There is obviously more to it, but these are my thoughts on the matter.

Now as a fellow 25 series Cell Phones should just not be allowed in secured facilities. You can have them in a lock box when you are in a secured facility but other than that it would be good to keep it on you. Also because not everyone lives in the barracks and the barracks are not always in the vicinity of work. Also taking your phone with you allows if an emergency happens and you have left for lunch or something for your supervisors to be able to reach you.

For staying in the barracks during the work week. I am sorry but my answer to that would be no as well. Unless the unit is on lock down for and event that happened or the Soldier is pending action under UCMJ they should not be required to stay in the barracks when not at work. Personally I have worked a 12 hour shift and then went bowling at a bowling alley after as a way to blow off steam and as therapy. You confine Soldiers to their barracks you are going to create a lot of unrest. There will be more issues that occur because the Soldiers will not be able to go anywhere or do anything. There is a reason in units where they have missions that could go from standard 9-5 or 12 hour shift to full blown everybody is coming back they have a maximum distance And guidance for the timeline to get back to work.
