Employee was 58 years of age at the time of the hearing before the administrative law judge. Employee worked for employer for approximately 30 years. During most of his time working for employer, employee worked as a maintenance supervisor. Employee's duties included supervising the other maintenance workers and performing maintenance tasks. Employee estimates he split his time in half between administrative and general maintenance tasks; employer's witness Russell Straughan disagreed and estimated employee spent 75 % of his time on supervisory or administrative duties.
We find employee's testimony more persuasive than that of Mr. Straughan as to the nature of employee's work duties. We find that employee spent half of his time on administrative tasks and the other half on general maintenance duties, which included
cutting grass, unloading trucks at the book store, plowing snow in the winter, leaf removal in the fall, trimming trees, power washing buildings, stripping and waxing floors, painting, cleaning walkways, gardening and mulching, operating chainsaws, hooking and unhooking mowers, and driving dump trucks.
Employee described certain tasks which he performed frequently. Employee was responsible for cutting grass almost every day during the spring and summer; employee operated the mower for about 6 hours per day. Employee repetitively used his arms and shoulders to maneuver the levers on the lawnmower.
In the winter, employee was responsible for plowing snow. This task involved driving the plow trucks and operating the manual transmission as well as the levers to maneuver the plow blade. Employee described pain in his right shoulder that sharply increased during the winter of early 2010, when he had to plow a lot of snow.
Employee frequently helped set up and tear down events. This task involved setting up and tearing down a stage, chairs, and tables. The chairs stacked together, which required use of the arms at the shoulder level or higher.
The month of May was particularly hectic for employee and the maintenance crew. Employee explained that getting the campus ready for graduation required performing as many jobs in one week as the crew normally performed in one month, such as sweeping, mopping, waxing, painting, mowing grass, making sure parking lots were clean, and other tasks.
On May 6, 2010, employee reported to his supervisor that he felt he'd hurt his right shoulder in the course of his work duties. Employer sent employee to Dr. Frank Krewet, who took x-rays, ordered an MRI, and released employee to return to full duty. Employer then sent employee to Dr. Michael Milne for an independent medical evaluation. Dr. Milne diagnosed right shoulder impingement and right shoulder rotator cuff tendinosis and opined that employee's work is likely an aggravating factor in causing this condition, but not the primary or prevailing factor. Dr. Milne opined that employee should consider a cortisone injection and physical therapy; if this did not work, he would recommend an MRI of the shoulder. Dr. Milne returned employee to work at full duty. Based on Dr. Milne's opinion, employer declined to authorize any further medical treatment.
Employee sought treatment on his own with Dr. Michael Ralph on May 11, 2011. Dr. Ralph ordered an MRI, which revealed a full thickness tear of the posterior half of the distal supraspinatus tendon associated with partial tendon retraction, proximal long head biceps tendinosis without tendon tear or rupture, and mild AC osteoarthritic disease. Dr. Ralph recommended surgery, which he performed on June 7, 2011. Dr. Ralph released employee to return to work in a light duty capacity on July 18, 2011, and to work without restrictions on February 21, 2012.
Employee submitted the bills and medical records generated in connection with treatment for his right shoulder. Employee also provided testimony describing his course of treatment. At
