Always explain your reasons for leaving
“I left because I fell out with my boss,” is probably not that helpful a comment to write on your job application. Hunters’ recruitment recommends that CVs contain reasons for leaving each job. These reasons need to be valid. A CV should tell a story of a career. You can add a bullet point at the end of each employment: RFL (reason for leaving.)
The pet hate of employers and recruiters is CVs of “job hoppers”. This means that candidates don’t stay for an acceptable amount of time in a permanent employment or move on without a strong enough reason. A “job hopper” CV suggests a lack of employment stability and therefore the likelihood is that the person won’t be a long term prospect/return on investment.
