I think an employee when ends up being dismissed after receiving several complaints or warnings should blame himself for such negative happening. The moment an employee secures employment, he gives an undertaking to comply with all the policies and rules governing his workplace.When a person is about to be sacked at work , he must have been given several warnings and complain over his attitude at work or errors in his work, this could also be seen in the way staff relate with such person because some of them might have heard or seen signs about it.
