Implementation of wage stickiness without labor market

I am currently developing an NK model with Rotemberg price stickiness largely following Gali et al. (2007). I am wondering whether there is an easy/lean way of implementing wage rigidity without having to implement a full-fledged labor market with search and matching frictions as well. Any help is greatly appreciated. Thanks!

What do you mean? Galí’s textbook already covers sticky wages without search and matching.
