Wicklow has eco-warriors, Dublin has "squashers". That's what they're calling the 50 or so people occupying Squash Ireland, the former health and fitness club which went into receivership in December.
The Department of Education owns the Clontarf premises on which Squash Ireland had a 21year lease.
This expired in 1994, but the company continued using the facilities until a receiver was appointed. The club was closed without warning on Christmas Eve.
The squashers won't budge, says Sheila Browne, a housewife from Donnycarney, until the club is "handed back" to the Department of Education.
Mrs Browne had been a club member for 16 1/2 years. Her son and two daughters were also members. Like many of the club's 400 subscribers, Mrs Browne paid her fees in December.
"I was mad when I heard about the receivership. Everyone said there was nothing we could do. But that is the wrong thing to say to me. I knew I had to do something," she says.
She organised meetings, attended by local TDs, where the director of another club, Westwood, proposed taking over the centre. Last week the receiver, John Gleeson and Company, placed an advert in this newspaper offering the premises for sale.
"They cannot sell it," a Department spokesman told The Irish Times. "It is not theirs to sell".
Mrs Browne made a few phone calls and since last Sunday evening she and a growing group of ex-staff and members have been using the club.
Outside, posters have been attached to the windows. "Peaceful Protest on Here" one reads. Another on the door says that it's "aerobics and squash as usual".
Well, almost. Visitors must knock, the doors are quickly unlocked and then hurriedly closed behind them. The squashers are camped in the reception area.
On the table are biscuits, milk, tea-bags and other essentials. Sleeping bags have been folded neatly on the floor. A two-ring electric fire provides the heat.
There are heaters in the squash courts, too. A lone portable radiator and an industrial gas blowheater provide warmth for the six squash players and 10 people gathered for an aerobics class on Wednesday evening. There is no hot water at present but, smiles Mrs Browne, "the sauna works".
Anne Lawless worked as an aerobics and gym instructor with Squash Ireland for seven years. "There had been rumours, but I suppose we just didn't want to believe them. When I got the phone call on Christmas Eve I was devastated," she says. Neither Ms Lawless nor any club staff were paid for December.
"I was in bits when I heard," says Bill Lowe. He had been a member of the club for 20 years and had paid his £325 membership fees in September. "I agreed straight away to the sit-in. It's women during the day and men during the night".
The last time Vicky Barrett, wife of Derek McDowell TD, was involved in a sit-in protest was at the library of her alma mater, UCG.
The couple had been members for eight years and paid their membership - £490 for husbands and wives - in December.
"There was a great atmosphere here as it is smaller than most other clubs," she says. "The sit-in is a good idea. We'll just have to wait and see what the receiver is going to do."
