TOPEKA, Kan. (AP) — A Kansas Senate committee has approved a bill to limit bargaining between state agencies and public employee unions and to prevent such unions from collecting dues through paycheck deductions.

The bill endorsed by the Commerce Committee on a voice vote Thursday also would keep state and local agencies and school districts from making many other paycheck deductions. The list includes contributions to charities such as the United Way.

The proposal originally would have barred only deductions for union dues, but committee members said it’s fairer not to single out unions.

The bill would limit collective bargaining between state agencies and employees to minimum wages.

Supporters say the bill protects taxpayers. Critics see it as an attack on unions.

The bill goes next to the full Senate for debate.
