Miss Johnson Miss Johnson was the young headmistress of Weatherfield Comprehensive . Her first interaction with the residents of Coronation Street was in September 2001 when English teacher Charlie Ramsden was going through personal problems and drinking heavily . Her pupils noticed and one of them chalked " Ramsden is a wino " on the board . Without any proof , she blamed neighbour Todd Grimshaw with whom she had an abrasive relationship already . Mother Eileen was asked to attend a meeting to discuss the matter and , when the Grimshaws both lost their tempers , Todd was suspended for five days and Eileen was barred from school premises . Nevertheless , the incident alerted Miss Johnson to the fact that she may have a teacher with issues on her hands and urged Charlie in no uncertain terms to seek help . Under pressure from Sarah Platt and Candice Stowe , pupil Luke Ashton admitted to being the one responsible for the graffiti and a second parent - teacher meeting was convened at which Charlie was astonished to see that Luke ' s mother was her own natural mother Pam Hargreaves ( Charlie having been adopted and only recently traced her birth mother ) . The incident did nothing to harmonise the fractious relationship between mother and daughter and Miss Johnson suggested that the pair try to sort their problems out between them . By the following April , Charlie ' s drinking problem worsened , exacerbated by husband Matt Ramsden ' s infidelity with Maxine Peacock , and both pupils and teachers started to notice again . Suspecting something herself , Miss Johnson asked fellow - teacher Ken Barlow if he knew anything but he denied all knowledge . Having caught her drinking heavily in the Rovers and then swigging from a vodka bottle in school , he felt he had no option but to report the matter to Miss Johnson who suspended Charlie from work . She felt she had no option but to resign and Ken , only in the position temporarily so far , was asked to increase his hours to take her place . When another teacher , Janette Forster accused Ken of reporting Charlie in order to take her job ( although Charlie had told Ken she bore no grudges and had brought it on herself ) , troublesome pupil Aidan Critchley overheard and a year - long conflict between the two began . Miss Johnson asked Ken to apply for the full - time , permanent position which he duly did and a few weeks later she asked him to become a Senior Pupil Mentor offering one - to - one counselling sessions to pupils who needed more support . Ken accepted the position while admitting to his growing problems with Critchley . Miss Johnson sympathised as several teachers had similar problems with the boy . A few day ' s later though , she had to intervene in one of Ken ' s lessons when Aidan caused havoc by suggesting that Candice slept around with the boys . Miss Johnson , not realising that Ken was in the room , brought the class to order and Aidan admitted to Ken that it was his mission in life to drive him out of the school . As part of this " campaign " , Aidan deliberately damaged Ken ' s car . He sent to Aidan ' s house to speak with his father , Bob , but his father proved to be just as loutish and the meeting ended acrimoniously . Bob complained to Miss Johnson about Ken and she reprimanded him , suggesting that he might not be up to the mentoring role . Ken ' s problems with Aidan were brought to a temporary end though when Peter Barlow visited Bob Critchley and threatened him if he didn ' t bring his son to order . By the following September , trouble between Ken and Aidan flared up again . A temporary truce had been established when Ken got the boy a work experience placement at Coronation Street Garage but he used this as an opportunity to copy Ken ' s car keys when it was in for a service and then use the vehicle for joyriding . Out one night with Sarah Platt , he was involved in an accident in which Sarah was badly injured . Everyone was suspicious of Aidan but as his fingerprints were on the vehicle legitimately , the police had no positive proof . Nevertheless they took him away for questioning during one of Ken ' s lessons , much to his satisfaction . To Ken ' s horror though , Aidan was quickly released and came back into the class , as cocky as ever and taunting Ken that the liberalism of several decades perpetuated by people like him had enabled Aidan to get off scot - free . Driven beyond endurance , Ken forgot his principles enough to punch the lad and break his nose . Ken immediately confessed what he had done to Miss Johnson and offered his resignation on the spot although it was not accepted pending a court hearing as Aidan had reported the assault to the police and Ken was charged . He appeared at Weatherfield Magistrates Court in January 2003 when he pleaded guilty and received a conditional discharge for a period of twelve months . Prior to a disciplinary hearing afterwards in front of Miss Johnson , which Ken didn ' t bother to attend , he submitted his resignation again , this time in writing , and left the school .
