A sit-in is underway at Mount Carmel Private Hospital following it's closure earlier this evening.
While the majority of the hospital's 320 members of staff finished their last shift this evening, it is understood a small number of people are engaged in a sit-in.
A sit-in was first mooted following a public meeting last night.
The move comes just after staff at the private hospital finished their final day at work.
There were emotional scenes as the majority of the 320 staff members finished up their shift before saying a sad farewell to each other.
Staff at the well known private hospital in Churchtown, South Dublin, were informed a week ago that they would be made redundant following the appointment of a liquidator to the hospital.
Some 200 of these yesterday received an email informing them that today will be their last day of work.
Last night, several staff members said that they had "hardly slept" since last week and that security at the hospital has been noticeably "heightened" over the past number of days.
They were informed this week that may face a six-month wait before they receive their state redundancy payouts which will range between €5,000 and €20,000.
Marie Therese Mooney said that she has been working in the finance department of the hospital for eight years, and that she is still "shocked, disappointed and sad".
"We are all just hopeful that someone will come up with a plan, give us an answer and maybe make someone accountable for this," she added.
