Employment outlook is way of looking at how an employment sector will be in the future. So people look at how industries are growing or declining in certain areas (geographical included) I guess for a teacher, they would look at things like number of schools in an area, how the population is growing, are new schools being built, all things that would increase teaching opportunities. By contrast, if certain industris production is slowing, then the employment chances aslo decrease. They maye also look at things like how many people are applying for each single job.
Maybe how you think it'll turn out, how you feel about it? That's my best guess.
you're kinda smart huh?
