Jackson's return to the Victoria Ground was as assistant manager to the club's new manager
Bob McGrory in 1935, a position he held until 1939. In November 1950, he took his first full managerial role at
Wrexham. He made history by giving debuts to his twin sons
Peter and
David. Jackson Senior moved to
Bradford City in February 1955 after
Ivor Powell was sacked. Both his sons followed him from Wales to West Yorkshire. City were forced to apply for re-election in Jackson's first season following a poor run of form under Powell. Jackson's first full season saw the team come 8th in
Third Division (North) followed by a 9th-place finish in
1956–57. In
1957–58 the club recorded its best post-war position by coming third. He was asked to manage the
Third Division North representative team in October 1957. The leagues were re-organised the following season and City's positions dropped to 11th and 19th in
Division Three before the club were relegated in
1960–61. Jackson left the club in March 1961. His two sons left with him. Peter Junior had played 199 league games, and David 250 scoring 61 goals. The pair moved to
Tranmere Rovers. Jackson Senior returned to Stoke City as a scout. In March 1969 he moved back to Bradford again as a scout. ==Career statistics==
