Bear in mind in the UK degrees called "English language" aren't usually language learning degrees, but courses in essentially applied English linguistics (sometimes they will also have aspects of communications/creative writing as well). Some will include English philology proper e.g. at Oxford, where you'll learn middle or Old English in first year, and may continue with both thereafter. Thus they're a bit different from modern foreign languages courses like French or German in the UK, where you will be learning the language as well as about the culture, literature, history, etc, of that country (and others that speak the language).
In general terms languages degrees aren't inherently better or worse than any other degree subject as far as generic concepts of "employability" go, because as with any degree the main determining factor in your employability as a graduate will not be your degree subject (or which uni you studied at), but in the depth and breadth of the work experience you undertook during the course. Simply graduating without having done a single internship/placement/period of work experience/etc will make you a fairly unappealing prospect to employers, no matter where or what you studied.
Language degrees do however offer, in the longer term, the potential benefit of having learned a foreign language up to a given level, and also evidencing language learning ability generally, which may make you more able to work internationally. That flexibility may give you additional options later in your career that others without that background wouldn't be able to pursue, and may also make you a more appealing prospect for some roles initially where language experience is beneficial.
