pre FIRE I basically worked at 2 organizations:
Very large telco type company: base of 3% + merit. Usually was about 6% early in career and dwindled to about 4.5% as you neared the top of the pay bands. This came with yearly bonuses of about 3-8% and on-call pay.
Smallish ISP (or as small as a national ISP can be). 3%. Never more. Never less. No bonuses. No call pay.
