Schools are facing a dire teacher shortage. Less competitive pay for Gen Z and young millennials could make it worse.

• Amid teacher shortages, ADP's Nela Richardson said it's tough to get young people to enter the profession.
• A new ADP Research Institute report showed how teacher pay compares to the pay of all employees.
• Teacher pay as a share of the pay for all employees aged 20 to 25 has greatly fallen over the years. 

There's a shortage of teachers, and young adults could be shying away from the profession as teacher pay becomes less competitive.
