IL SB2622

Amends the Workers' Compensation Act to require employees required to travel for work to be actively engaged in job duties at the time of injury to receive benefits.

Defines "accident" as an occurrence arising out of employment, resulting from a risk incidental to employment, at a time and place reasonably required by the employment.

Defines "injury" as a medical condition arising out of and in the course of employment that must be established with reasonable medical certainty, and requires the compensable injury to be the major contributing cause (more than 50% responsible) of any resulting injuries.

Specifies that travel to and from work and injuries during paid or unpaid breaks are not compensable as arising out of and in the course of employment.

Excludes injuries resulting directly or indirectly from idiopathic causes (self-originating conditions unrelated to employment) from compensation, and limits coverage for pre-existing condition aggravations to periods when the aggravation remains the major contributing cause of disability.
