A colleague at Luxx Light Technology, where Mrs McHugh worked as a PA, said that everyone at the firm was in shock at her death. She had only recently returned from maternity leave.
Chief Executive George Leonidou said: "She was a lovely lady, always smiling, she loved her family and her children. She was a brilliant PA and had been with me for four years. She was the most conscientious worker I've ever had.
"We all miss her. The whole office and warehouse is in shock and we're just trying to work our way through it today. Yesterday was a very bad day.
"She will be sorely missed by everyone who knew her."
He added: "She was non-confrontational, but she would have been fiercely protective of her children.
"She was blocked in trying to get her five-month-old daughter into the car and another car had parked, so that she couldn't do so.
"I know that Christie would have asked the person in a polite way to move their car. But I was told the other person was very aggressive and totally out of control.
"However bad your day has been it clearly doesn't give you the right to do that to someone in front of their children.
"We all miss her here, but we're talking about someone leaving a five-month-old daughter who will never know her mother, a five-year-old boy who is constantly asking when mummy's coming back."
