"This means sitting down with the employee and setting targets and expectations.
"A review period should then be set which allows the employee a reasonable opportunity to meet those targets within the timeframe."
If the employee does not meet those targets a written warning is usually the appropriate response.
"The employer should then set another review period and assess the employee at the end of that period to see whether the targets have been met.
"Any failure at this stage would lead to a final written warning and the next time around would be dismissal if the targets and expectations had yet to be met."
Smyth says it is important to follow the correct process. "Any failure to follow the correct process may lead to a personal grievance."
