Two things:

1) If there is a legitimate concern that some crisis will arise and be heavily exacerbated by you not being at work during vacation, that is an operational problem in the organization that needs to be dealt with. Who is your backup? What would happen if you suffered a medical emergency and were not in the office for a month? How would they deal with that?

2) It sounds like your expectations and values do not align with your manager's expectations and values. This is something that you should resolve with your manager or consider finding work elsewhere.

The intent of vacation is for you to recharge mentally and emotionally. A vacation where you are still plugged in, still on call, still expected to work, is not much of a vacation.
