Pros
They have a lot of contacts so getting you work is usually consistent. I'm paid decently well.
Cons
Firstly, the process they have you go through to get paid is stupid. You have to fax time-cards in by Monday at noon. Not many people have fax machines anymore. I don't see why they can't be more efficient and let us email it to them. This is the 21st century NOT the 20th century. Secondly, it's hard to get a hold of them. They don't answer calls much. Thirdly, you're not trained well. They think that just because you have a degree, you know everything. However, that is never true. You can't learn everything in a classroom when you're in school. There are things you can only learn from experience. For example, when it comes to the rules in an elementary classroom, you have to learn those from asking questions and experience. But Delta t doesn't really understand that. Delta T gets disappointed when a teacher you work under complains about you. What Delta T should be doing is helping you learn those rules in order for you to have an opportunity for full-time employment at the job site they send you to. But they'd rather blame you and keep themselves clean to boost their ego.
