Siobhan Condon, 41, bragged about the power she felt at breaking up the family and revelled in the judge giving the parents a ‘massive rollicking’.
She even referred to the solicitor in the case complimenting her ‘fine nails and shoes’ before saying she was about to ‘do the mammoth grim task’ of removing the youngsters from their home and signing off with three kisses.
The children, all aged under ten at the time, were put into foster care following the court hearing last year.
Their mother reported Miss Condon’s comments to Essex County Council after spotting them on the social worker’s Facebook page, which was open to the public and gave enough information to identify the family.
Family proceedings are normally held behind closed doors and shrouded in secrecy.
The Health and Care Professional Council found Miss Condon guilty of misconduct and the local authority decided not to renew her contract.
However, she has not been struck off. Instead, she must be closely monitored by a line manager for a year.
Tory MP Simon Burns yesterday questioned the leniency of the punishment, saying: ‘There are some very difficult cases … where there are no winners and it seems incredible that someone in a position of trust and responsibility should post information on Facebook … to gloat is totally inappropriate.
