But see Peterson v. Arlington Hospitality Staffing, Inc., 2004 WI App 199, 276 Wis. 2d 746, 689 N.W.2d 61, 03-2811. Cessation of employment under sub. (2) (g) 2. does not require that the employee no longer be employed, but requires that the employee no longer be employed in the employment that contributed to the disability. If that is the case, the employer that caused the injury is responsible. North River Insurance Co. v. Manpower Temporary Services, 212 Wis. 2d 63, 568 N.W.2d 15 (Ct. App. 1997), 96-2000. Sub. (2) (g) sets the date of injury of an occupational disease, and s. 102.42(1) provides that medical expenses incurred before an employee knows of the work-related injury are compensable. Read together, medical expenses in occupational disease cases are not compensable until the date of injury, but once the date is established all expenses associated with the disease, even if incurred before the date of injury, are compensable.

It merely sets out a mechanism for fixing the time, occurrence, or date of an injury for purposes of identifying the proper employer against whom a claim may be made. White v.

LIRC, 2002 WI App 277, 258 Wis. 2d 665, 654 N.W.2d 306, 02-0031. A company in the business of loaning employees was not a "temporary help agency" under sub.

The statute requires that the employee is placed by the temporary help agency to the employer who will supervise that work. M.M. Schranz Roofing, Inc. v. First Choice Temporary, 2012 WI App 9, 338 Wis. 2d 420, 809 N.W.2d 880, 11-0345.
