According to WhyY.org, more than 200 custodians who clean 22 Philadelphia public schools have authorized a strike. Each side is accusing the other of using scare tactics.

The contract employees work for Team Clean, and say they make much less than their counterparts who are employed by the school district. Valerie Long is vice president of the Service Employees International Union, local 32 BJ. Long says management is using illegal scare tactics to keep workers from speaking to union representatives.

"It's really gotten stalled because of this harassment of our union members. It really just slows things down and makes workers afraid to take action."

Long says the workers make between $9.70 and $11.25 an hour. They want a wage increase and better benefits.

Team Clean says the union used scare tactics to get workers to authorize a strike. A spokesperson says the company will continue to clean the schools even if a strike occurs
