The County shall continue to provide its present long term income protection plan for permanent employees at no cost; provided, however, that in order to be eligible, employees must have been employed by the County for 3 or more years. The maximum monthly salary cap is $2400. The County will extend coverage to all otherwise qualified permanent employees. Benefits for psychiatric disabilities that result from stress, depression or other life events are restricted to 2 years. However, a disability resulting from certain chronic psychotic disorders or a disorder with demonstrable organic brain deficits can qualify for benefits payable up to the age of 65. For disabilities commencing on or after January 1, 1988, the 120 day disability period required to qualify shall no longer require continuous disability but shall be cumulative for any single medically verified illness or injury within a period of 6 full months from the date of the disability’s onset. The onset date shall be defined as the first workday the employee was unable to work.
