The union intends to carry out its threat for a strike at the flagship Seibu Ikebukuro store in Tokyo on Thursday, according to a union member.
A person with direct knowledge of Seven & i's plan said its board would meet on Thursday to officially decide on the sale.
The union received no reply and would therefore carry out the strike on Thursday at the flagship store, where about 900 union members are employed, he said.
Fortress had initially planned to spend around 250 billion yen ($1.71 billion) on the acquisition but is likely to have lowered that price to about 220 billion yen, the source said.
