Newcastle Falcons have placed all players and staff on furlough due to the coronavirus pandemic.
Bosses at the Kingston Park club have written to employees to explain the move and ask for formal consent from all staff.
The Falcons held a perfect record and a comfortable 18-point lead in their bid to secure an instant return to the top flight.
The cancelled Championship season means they are now awaiting an RFU decision as to whether they will replace Saracens in the Premiership next term.
However, the current uncertainty has led to the Falcons look to place players and staff on a leave of absence to cope with the financial impact of the pandemic.
The letter seen by PA news agency reads: “We hope that we will be able to facilitate a return to work once government advice and the business need supports this.
“However, we must acknowledge the current uncertainty and the constantly developing landscape and we cannot offer any assurances or timescale at this stage.
“The company acknowledges that this is a difficult time for all employees across the country, but the support provided by the government is welcomed and I am sure it will provide some reassurance to you during this difficult time.”
The RFU has ended the 2019-20 season at all levels barring the Premiership.
Premiership chiefs are hoping to complete their season, but there is no ruling yet on Championship promotion and relegation.
A Falcon spokesperson said: "Newcastle Rugby Ltd, which includes Newcastle Thunder, Newcastle Falcons and its associated charity, Newcastle Rugby Foundation, is working with all staff to put together a plan aimed at ensuring long-term job retention and the ongoing stability of the business.
"This plan will incorporate government help via the furloughed worker scheme for some staff members, and salary reductions.
"This is to ensure that we are in a strong position to move forwards when rugby resumes.
"We thank our staff members for their understanding during this difficult period."
