Legislation to let employers pay some young workers less than the minimum wage hit a roadblock Thursday amid questions of whether it will discourage people from going to school.

Rep. Travis Grantham, R-Gilbert, was forced to withdraw his HB 2523 from consideration by the Senate Commerce Committee after one Republican balked at supporting the measure as already approved by the House. Sen. Tyler Pace, R-Mesa, said he worries that the bill sends the wrong message about education.

That’s not all. Pace said he wants to be sure that companies don’t replace their minimum-wage workers with those who, under HB2523, could legally be hired for less.

Pace’s vote is crucial.

All three Democrats on the eight-member panel were expected to vote against the measure. Without Pace, the bill would die on a 4-4 vote.

But Pace told Capitol Media Services Thursday he’s going to meet with Grantham to see if his concerns can be addressed and he can support the measure.

The legislation creates an exemption to the 2016 voter-approved law which boosted the state minimum wage from $8.05 an hour at that time to $11 now. It will increase automatically to $12 in 2020, with future increases tied to inflation.

What Grantham wants to do is allow employers to pay the federal minimum wage of $7.25 an hour for full-time students who are younger than 22 and work no more than 20 hours a week.

Grantham, backed by business lobbyists, said the minimum wage increase has meant that many companies can no longer afford to hire young people to do basic tasks. He argued that permitting employers to pay something below the state-mandated minimum will help create employment opportunities for students.

“A lot of them can’t get jobs because the lowest-paying jobs went away because people can’t afford to pay somebody $15 an hour to bag groceries,” he said.

Pace, however, said he sees flaws in all that.

“We don’t want businesses to use this as a way to unemploy people who are employed at a certain rate,” he said, replacing $11-an-hour workers with those who can legally be hired for $7.25.

But that’s just part of his concern. The real problem, Pace said, is linking a lower minimum wage to being a full-time student.

“The bill, the way it’s written, would say, ‘We’ll pay you more if you don’t go to school,’ ” Pace said. “To me, that appears an incentive to not go to school.”

He suggested flipping the bill – providing for a sub-minimum wage for those who are not in school – might send a more desirable message.

“The governor and both chambers (of the Legislature) are working heavy on making sure that we educate and incentivize kids to go through the process of education to improve their outcomes to be able to provide for their families in jobs that would be above minimum wage,” Pace said. “I want to be sure that, at least for me, that anything I support doesn’t de-incentivize kids to go to school.”

Grantham does not dispute that his legislation allows one rate of pay for part-time workers who are full-time students and a higher rate for those who are not. But he said there’s no rational basis for Pace’s objections.

“I don’t know how one could think that, in order to make more money, someone’s then going to not go to school to make $2 to $3 more an hour, but they’re still going to work less than 20 hours a week,” he said. “If you do the math on 20 hours a week, and it’s only a $2 to $3-an-hour difference, you’re talking about $40 to $60.”

Pace said he’s generally in favor of what Grantham said he is trying to do: reduce youth unemployment.

“How we do that?” he said. “That’s yet to be determined.”

Grantham defended targeting his legislation for a sub-minimum wage at full-time students.

“Students are more like seasonal workers,” he said, including people who come here from all over the country and the world. And that, he said, puts them in a special class – one that he believes should not have to be paid the full voter-mandated minimum wage.

“I’m not concerned with capturing everybody,” Grantham said.

“I’m concerned with folks who come here for a small amount of time, on a temporary basis, and are looking for part-time work,” he said. “It’s that simple.”
