As a former employee of some of the largest European corporations I can assure you they usually operate way pass legal boundaries. The absolute worst that can happen to them is to get fined, which is not enough deterrent as usually the fines eat a tiny portion of their profits. No one goes to jail either, a major corruption scandal may send a CEO on early retirement with a full compensation package and/or to work for a competitor. So assuming European companies won't spy on employees just because it is illegal is pretty naive. Always assume you are being monitored by your employer, because more likely than not you are.
