Pros

If you’re in a new school district and haven’t been able to get a job teaching, subbing for ESS is a good start.

Cons

You aren’t always assigned to the teacher your originally accepted the job assignment for.

Pros

-Relatively quick hiring process -You get to know your school district better -Pleasant school staff once you find your favorite area

Cons

-No training a lot is learned after a consequence or on-site Ex: I learned that you have to call ESS for cancellations instead of using the willsub+ app AFTER being blacklisted from my first school. -Delayed or incorrect paychecks for up to 2 - 4 weeks at a time -No HR assistance , don’t bother reaching out if ESS is at fault -No reliable upper management contact Ex: I called 3 days straight regarding a paycheck affecting my housing and a missing days work. They did not get back to me for 2 days. Customer service apologized stating they couldn’t do anything. -Your account will be deactivated constantly for any reason including missing a call from them. Very backwards given they don’t answer calls. -You don’t actually choose when you work -They require up to 15 UNPAID minutes before the start of the assignment for you to arrive. -You may have to stay after the assigned time UNPAID -I am disabled and took this job because of the implied flexibility being extremely vital to me but its worse than a 9-5. -no pay over breaks or holidays -retaliation seems to be common place or just pure lack of empathy. Wouldn’t be surprised if i am let go after this review. If you work for them don’t do it full time no matter what just use it as an occasional side job.
