I think Nick pretty much left Restless Style in Phyllis' hands which is why you see her making or getting phone calls alot like the call she got when Sharon was breaking down at her place on yesterday's episode.
Besides, do we ever see anyone at work lately, they are all to busy drinking coffee at Crimson Lights, eating at the Althletic Club, sleeping around on each other or ploting their next act of revenge to be bothered with work.
The only time it seems we see them at work is when it's convienant for the script.
