For the record
The Normal Actuarial Cost for the public service plan in 1980 was 16.2% of salary. That was what was needed to pay for the pensions.

Employees were told that 6 and one half % of their salary went to pension, matched by government as employer. Plus 1% of salary for indexing, matched by government as employer. Total 15%. 

So it seems that total compensation was take home pay before taxes plus 16.2% of salary plus other benefits.
