Updated at 5:55 p.m. with Schnucks response

Teamsters Local 688 has filed charges of alleged unfair labor practices related to Schnucks' decision to layoff 190 Bridgeton warehouse workers and replace them with non-union workers.

Schnucks, however, disputed the allegations.

"The union accusations of wrongdoing are meritless, and we intend to defend these charges vigorously," company spokesman Pal Simon said in a press release.

Last month, Maryland Heights-based Schnuck Markets notified the union of the looming job cuts when the grocery store chain's new distribution center opens in Kinloch in June. A third-party logistics provider, XPO Logistics, will staff the Kinloch facility with non-union workers.

In its charges filed with the National Labor Relations Board, the union alleges Schnucks refuses to recognize its contract that requires workers to be offered jobs when the chain hires a subcontractor or if a facility is relocated, said Mike Goebel, secretary and treasurer of Teamsters Local 688.
