Examples of wage suppression

What type of wage suppression has anyone seen,
experienced or suspected from employers, good boatmen seem to be in demand, shortages all
over, better time than ever to keep demanding
higher pay

Are you questioning why the fundamental rules of macroeconomics seem to no longer work?

Aren’t we all?

Probably so in the big scheme of things,looking for more specific behind the scenes tactics
like failing to hire new personnel or attracting
any for that matter which results in personnel
asked to work longer that scheduled etc, collusion
would be another example
