I was actually referring to Kensdad, who said: I don't consider being the lead in a Broadway production to be a "normal" job. I think there's an additional responsibility/burden that comes with it. If that means that you run down to Florida for only a day or two instead of four days, then that is part of life in your chosen profession.
And: I think Salonga missed the mark on this one, and if she were going to be out for an extended period (other than illness), then there was a moral responsibility to notify audiences well in advance
This board is full of self-appointed arbiters of what is right and what is wrong. But whatever someone might think, Salonga cannot compel the producers to make an announcement weeks in advance that she will be out. If I recall correctly, she informed her fans several days in advance, via Twitter, that she was going to be out. Twitter is a great resource for artists to do that these days, but really, they are under no obligation. And an anonymous audience member acting like he has the right to tell an actor how many days they should take off leaves a foul taste.
