UPDATE 1-Teamsters union files charges against PepsiCo with US labor board

(Adds PepsiCo's response in paragraph 3)

April 19 (Reuters) - Teamsters local unions in three states filed unfair labor practice charges against PepsiCo with the U.S. National Labor Relations Board, the union said on Friday.

The charges were filed by five Teamsters local unions in the states of Illinois, Indiana and Iowa over PepsiCo's work rules that prohibit workers from discussing wages, hours, or other terms or conditions of employment, according to the union.

"We have been negotiating in good faith with Teamsters across Illinois and Indiana to reach mutually agreeable collective bargaining agreements," PepsiCo Beverages North America said in an emailed statement to Reuters and added it had not committed any "unfair labor practices."

Unions have seen a resurgence after a decades-long decline and some, including the Teamsters, have won significant new contracts.

Labor groups have also been an important talking point amid the ongoing 2024 U.S. presidential campaign. Teamsters leaders met with U.S. President Joe Biden last month, weeks after his Republican rival Donald Trump met the union to seek their endorsement.
