Findo;
The freqs aren't that bad most of the time since if you are busy you split off the sectors. However, on the midnight shifts you can't split due to lack of staff. That is one of the times it gets a bit bad... Of course, there are some days when you can't get enough folks in due to illness to split everything either... <sigh> Then you just try to put everyone on one freq a much as you can. The satellite airports that my brother in FWA speaks of is normally used over here so that you can talk to aircraft on the ground to give clearances...
One other thing though, we are pretty much expected over here to work a rather large share of traffic compared to what I have seen over in Europe... It's a cost thing mostly. We always try to get by on the least possible cost.
