The sexual health charity Brook, which completed an 18-month restructuring process in April, will decide after October whether to make redundancies. It employs about 660 full and part-time staff.
Sixteen of the 17 independently constituted Brook charities agreed to become one organisation. Simon Blake, the national director, said the merger would enable Brook to achieve the goal it set in 2009 of doubling the number of young people it reaches.
"To do that, we needed to have a nimble organisational structure that wasn’t defined by geographical boundaries," said Blake.
He said Brook would assess its capacity and resources over the next few months before making any staffing decisions. "We have committed to there not being any redundancies before October," he said.
Blake said the charity was still in discussions with Brook Northern Ireland, the only Brook that chose not to join the new structure, about the relationship between the two organisations.
