The BBC are reporting that unionised workers at Greater Manchester-based JJB Sports plan to go on strike next week calling for better wages and conditions, according to the GMB Union.
The GMB said 266 workers at the JJB distribution warehouse in Martland Park, Wigan, are taking action on Tuesday and Thursday.
There will also be a continuous ban on overtime from Tuesday morning as workers protest against a 3% pay rise.
Union negotiators are seeking a higher basic rate for warehouse staff.
They are also calling for equal access to a bonus scheme.
The company has about 430 shops in the UK and its executive director is David Whelan, owner of Wigan Athletic and its ground, the JJB stadium.
Higher basic wage
The GMB said the strikes were "a warning shot" to JJB and pledged further action with staff prepared to do "whatever it takes" to secure better working conditions.
GMB regional organiser for Lancashire Sandra Blight said: "JJB Sports workers could not be clearer about their wishes regarding pay.
"They want a higher guaranteed basic wage for all workers in the warehouse and equal access to a bonus scheme for all workers."
A strike last year over pay was averted at the last minute when an offer was accepted by 51% of staff.
