Peter Frost is a 52-year-old maintenance mechanic with 25 years of service in the Toronto operation of Wilson Bros. He originally completed his mechanic apprenticeship in England. Peter is known as a likeable and knowledgeable, technically competent tradesman. He has significant leadership skills and has been interested for some time in the notion of having a union represent employees at the plant and was successful at leading a union organizing drive some years ago. Unfortunately, Peter doesn't seem to want to come to work, and when he does he is often late. Over the past four years, Peter has missed over 100 shifts due to absenteeism, and was late an additional 53 times. The records also show that on at least 25 occasions, Peter not only missed his shift but didn't bother to advise his supervisor in advance that he would be absent. The Company has noticed this deterioration of performance over the past four years. It seems to have been getting progressively worse. There seems to be a pattern of Monday and Friday absences and there are strong and persistent rumours from other employees that Peter's breath smells of alcohol on a regular basis.
