Voisins Department Store will trial a five day working week throughout February.
It will see the store close its doors to shoppers on Sundays and Mondays between 30 January and 27 February.
Chairman of the store, Gerald Voisin says the move is down to a shortage of staff.
"Our staff have worked extremely hard over Christmas and we thought that we would try and ease the problem by only operating five days a week instead of six"
Gerald says that he hopes that other retailers in the island will be watching Voisin's trial closely.
"We are happy to share our experiences with other retailers to see if it works.
It all depends if customers who like to shop in the store can do that between Tuesday to Saturday and avoid the Monday.
Obviously, if we lose all the sales that we would make on a Monday then we might decide that the trial didn't work."
Mr Voisin says the news of a shorter working week has gone down well so far.
"The staff have received it positively, I think they're going to enjoy having two days off.
We will see how our customers will respond when we start doing it, if we don't lose any sales then that will be a great result for us."
Voisins is asking customers to give their feedback on the plan by calling or emailing the store.
