Couple of contractor employees placed in the stores department for loading/unloading and material feeding work resorted to slowing down. We tried to counsel them, but to no avail. After a week, we decided to take strict action, and two contractor workers who were playing a leading role were stopped at the gate. Now, things are returning to normalcy. The problem is that these contractor workers are very old, with 2-8 years of service. The contractor is also not playing a positive role. How can we get rid of the workers and the contractor, as every now and then, we are facing problems that cause our production to suffer, and we are forced to do overtime. On top of it, some of the contractor workers refuse to do overtime. Please advise.
