Earlier this year Jon was one of two members of staff threatened with redundancy in a restructure by Mail publisher Trinity Mirror, although the threat was later lifted.
However the company has since invited fresh applications for voluntary redundancy as part of its proposal for 19 job losses in Birmingham, and Jon has decided to bow out.
Jon told HTFP: “I am leaving the Post and Mail after more than 20 years, 17 and a half as Mail business editor.
“I have loved my time on the Birmingham biz beat but I think this is the right decision for me at this juncture.”
Jon is due to clock up 40 years in journalism tomorrow, having started his career at the Peterborough Evening Telegraph on 30 June 1975.
He first joined the then Birmingham Evening Mail in 1978 and had stints at the Coventry Telegraph and then the Wolverhampton Express and Star before rejoining the paper in April 1996.
Jon has long been regarded as one of the outstanding business writers in his region, having won the Business Journalist of the Year prize at the Midlands Media Awards on no fewer than nine occasions.
He is the current holder of the award, having also won the same prize in 2013.
As part of the current round of cutbacks in Birmingham and Coventry, each member of staff at the two centres was offered the opportunity to take voluntary redundancy, with a deadline of 16 June for applications.
It is understood that Jon’s application for VR was accepted by the company last week.
