A study was carried out in Mafuga forest plantation to assess the working conditions, physical workload and productivity of logging companies. Data were collected in a clear-felled 26-year-old Pinus patula stand. Time studies were undertaken for tree cutting and skidding in order to determine productivity. Data on physical workload were obtained through heart rate measurement using portable electronic heart rate monitor. Data on working conditions were obtained using ergonomic checklist and field observations. Productivity in tree cutting averaged 16.5 and 9.9 m3/hour for felling and crosscutting respectively using chainsaw. Production rate in skidding was7.2 m3/hour. These production rates were higher compared with public logging regime where past studiesshowed 9.6, 4.2 and 3.7 m3/hour for felling, crosscutting and skidding respectively. Working conditions were inferior compared with public logging regime. Workload produced 65% heart rate increase when chainsaw was used. This was a slight increase compared with public logging regime where physical workload was estimated at 57% heart rate increase for chainsaw use. Therefore, the increased productivity observed in this study was not due to improved working conditions but rather, workers were afraid of the employer. Supervisors were more interested in making sure that output increased irrespective of how it was obtained. Poor working conditions could be reversed by the government setting and implementing both practical rules and provisions regarding employment regulations.
