Hi,
there have been several complaints in different organisations of that nature here in Uganda and some in Tanzania,so dont get surprised of that,People differ so much,can u imagine others have been idenditified to have seasonal mind disorganisation.One of the roles of HR is to counsell employees whenever there is an existence of any disapproved characters,the aim is to help and retain for organisational effectiveness,if all reasonable and practicable means fail,just follow disciplinary procedure.
1. Request an informal meeting with her
2.Issue formal warning written letter
3.Issue formal warning letter the second one.
4.Just Dismiss,terminate the contract.
For more on this read the topic "Release from an organisation" in the New Edition of Armstrongs' HRM Practice Book.
Nice time.
