I dont understand what you mean by rest hours,in your work experience you only write down the work experience that you are claiming points for so for example if you worked in 4 jobs and you are claiming points for only 3 you will write those 3 in your work history and all the 4 jobs in personal history,you are only required to provide experience letters according to cic format only for the jobs that you are claiming points for,the rest are mentioned in personal history,in order for you to be eligible for fsw stream you have to have at least one year full time experience so its up to you to include your part time job in your work history or not,hope that helps
