At my place, reneging carries a significant negative tone (it is also where I learned the word). It is also deeply against the culture here to miss commitments willfully and without notice. In particular, one tentative but reneged new hire was on a visa from India. I'm not sure what happens there. Though I'm not sure if the visa was sponsored by my place or not.
