One of the employers that I worked for for 4 years, then took a sabbatical for 1 year and 8 months to pursue my Masters and then rejoined the employer albeit in a different Geography (US). Worked there for 9 months and returned to my home country and continued with the same employer for 9 months. The NOC remains the same across my time spent with the employer. Should I have different entries for work experience 1) before and after sabbatical, 2) different geographies or can I club them together? Do I have to provide separate employment reference letters for before and after sabbatical or one single letter explaining all my experience should do?
