I find that being asked to do other jobs, other than that for which you were contracted gives some added variety, and if you do a laborious job helps pass time during the day. The only thing that drove me to near breakdown with one employer was the constant 10 jobs at once, then of all things being shouted at for not finishing the first job, day in day out and also no praise 10 days holiday a year, 9 grand a year pay. and the BOSS 100G's
