My current p-doc works 4 full days a week and is accessible by e-mail (or I guess phone) when she's not in the office--the couple times I've e-mailed her about possible negative reactions to medication, she's gotten back to me within a day. I think she was on vacation a couple weeks ago, but I only see her monthly, so it hasn't affected me much. I'd be bothered if she was as inaccessible as your pdoc, bluebicycle.

My T I guess is semiretired and works full days M-W. She's had a few vacations, but usually only a week or so, so I haven't had to miss much time. I could generally contact marriage counselor if I'm having issues/in crisis while she's out of town (and vice versa).

MC works M-F (though I think only in the evening on Tuesdays) and every other Saturday for part of the day, I think. He's taken a few vacations (usually just off a week), though had to miss a lot of time--often at the last minute--in the past couple years due to his wife's illness (she passed away in late December). There was one period maybe 2 years ago when he canceled at the last minute (I had no idea what was happening with his wife at the time), then it took a long time to get him to reschedule. Like I left a voice mail, heard nothing for a week, and eventually had my T give him a note for me (they're in the same office), and then he finally called. So that was difficult because I had no idea when we'd be able to see him again (I think H and I were going through a bad patch then too). We then started having a standing appointment, so at least if he canceled, then we'd presumably just come the next week (rather than having to track him down to schedule).

If I didn't like him so much (and didn't have transference/attachment to him), I could see that having been a reason to stop seeing him. T actually said at that time that she had stopped referring people to him (she referred us) because he had to cancel so often (I assume others had complained to her about it).
