Tony Danker is reportedly planning to sue the Confederation of British Industry (CBI) over his sacking for complaints against his alleged behaviour.
The former CBI chief, who is Jewish, is consulting lawyers as he considers filing a potential claim against the CBI, according to The Sunday Times.
Employment tribunals must be brought within three months, meaning Danker, 51, has until July to launch his claim.
Danker was sacked after allegations of misconduct toward several employees surfaced.
In January, Danker argued that the allegations of misconduct, including sexual harassment, were unfounded, insisting there had been no sexual element to his relationship with a woman who complained about him.
Danker said it was "mortifying to hear that I have caused offence or anxiety to any colleague" but insisted it was "completely unintentional".
In a statement announcing his dismissal earlier this year, the CBI said Danker’s conduct had “fallen short of that expected of the director general.”
Danker was chair of the Union of Jewish Students from 1993 to 1994 and worked for the former Chief Rabbi Lord Sacks in the mid 1990s.
CBI president Brian McBride characterised Danker’s description of his termination letter as “selective”, and said the decision had been taken unanimously by the board on “very firm” legal ground.
The CBI declined to comment. Danker could not be reached.
