Hi Trisha,
Just start counseling and let the employee know these are your weak areas. Also, inform the employee that failing to improve and meet the required goals may lead to management making a decision. This way, the employee will be aware and mentally prepared. If things do not change, then there is no other option but to terminate.
Call the employee for a discussion and begin by talking about various topics. During the conversation, ask the employee how HR can assist in their job. This will prompt the employee to share their thoughts. Then, inquire if the employee is facing any challenges at work or home. Subtly address their performance. Hopefully, this approach will be effective for you.
