Federal Group will postpone its decision to stand down 1500 Tasmanian employees until Sunday "at the earliest".
In a letter to staff, managing director Greg Farrell said a decision would "likely" be made on Friday as to how the company would proceed while most of its venues are closed due to the coronavirus.
Its venues include Wrest Point, Country Club, Tourism, Vantage Hotels, Odyssey, and Network Gaming.
The letter says, "We appreciate that this is an unusual and distressing time for everyone.
"We want to ensure you that, despite these difficult circumstances, we are committed to supporting you.
"You can contact CONVERGE, our employee assistance helpline. This is a free and confidential counselling service and we encourage you to make use of it."
However, a Federal Group employee said when they contacted "Converge" an automated voice told them their call was not urgent and to try again later.

The Farrell family, who owns Federal Group, live in Sydney and are worth an estimated $715 million, largely due to their monopoly over Tasmania's poker machine licences.
Tasmanian Greens senator Nick McKim said the group had used the threat of workers' job losses in the most recent state election campaign, when Labor had campaigned to ban the pokies.
"Greg Farrell has sucked a literal fortune out of Tasmania over the decades," he said.
"He used his workers and venues to buy an election and is now throwing them under the bus."
Author James Boyce, who wrote an award-winning book about Tasmania's gambling industry and the Farrell family in particular, said the family should draw on their "enormous" wealth before sacking workers.
The company came under fire on Wednesday for its delay in ceasing to ask for rental payments for the use of its poker machines from pubs and venues that were forced to close.
Federal Group corporate affairs executive general manager Daniel Hanna said all Federal Group employees - casual, part-time and full-time - would have a job to come back to when its venues reopen.
"We simply have no work for most people at this point; following the forced closure of our businesses as a result of the government's shut down measures," he said.
"We are working through the official processes we are required to undertake to advise staff of a potential stand down and undertake consultation.
"The consultation process is taking considerable time and we will pay all full-time, part-time and casual employs for rostered shifts for the entire week, until Sunday night, regardless of whether their workplace is open and they can work, or not.
"Quite frankly we've got more important things to be worried about than the ill-informed opinions of long-term detractors, who are schadenfreude in their reaction to recent events."
