A teacher who stayed away from school by forging doctor’s notes has avoided being sent to prison. It was revealed in court that Kulvinder Billan forged half a dozen notes and a letter from a doctor so he could avoid teaching at a school in Northampton. The court heard the 31-year-old had a substantial amount of time off sick during his first academic year of 2009/10 but he found it difficult to go back to school in the following year.
