Cost-of-living adjustment (COLA)

What a COLA is and is not

A COLA protects value; it does not reward anything. Paying one says "standing still should not mean going backwards", which is why unions bargain for indexation and why wage floors (minimum wages, award rates) are reviewed annually against living costs in most systems. Merit, market and promotion increases then do their separate jobs on top. Employers who let inflation quietly erode real pay are running a stealth pay cut, and employees can do that arithmetic.

The employer's real decision

Few private employers formally index salaries; the practical question in inflationary years is how much of the increase budget is effectively COLA before differentiation begins. The honest framing helps: "3% protects value for everyone; the merit pool differentiates on top" reads very differently from a blended 4% that high performers discover barely beat inflation. Whatever the split, the annual wage-floor movements (each country's minimum and award cycles) set a hard floor under the decision for lower-paid roles.

Location and the remote wrinkle

Cost-of-living also drives location-based pay: the same role priced differently across cities, and the remote-work question of whether pay follows the person or the role. There is no consensus answer, only trade-offs between market logic (pay the local market) and value logic (pay the work). What fails is having no policy: ad-hoc answers to "I'm moving, what happens to my pay" accumulate into precedent nobody chose.
