Walmart kicked off sales at 8 p.m. Thursday, but employee walkouts could cast a shadow over the big retail day.
Walmart workers are asking for better pay and benefits.
They're being urged by union leaders across the country to join walkouts, which started Thursday night.
In Connecticut, demonstrations are planned at four stores in Danbury, Hartford, Milford and Norwalk.
The protests are expected to begin around 11 a.m.
Walmart said labor unions are trying to disrupt business.
