Do employers value your language skills?

Some airlines pay their staff a little extra for every language they speak, but other employers are entirely uninterested in their staff’s language skills. While it has often been argued that these skills offer a competitive advantage and that one can even expect to be paid a premium, this seems to vary a lot from country to country and from industry to industry. In some jobs communication may be less relevant, but more often language skills are beneficial in various ways.
In my own experience speaking Scottish Gaelic, a minority language, gave me the competitive advantage to get a job at the BBC. While my knowledge of several other languages has repeatedly benefited my work, it would seem that appreciation of the skills varies.
