These aren't the normal hotel standbys. This is a tactic they use during peak to prevent you from dropping or trading against max OT.

95% of these hotel standbys will not get filled. Only time they get filled is when guys actually pick them up. Otherwise scheduling never assigns anyone these hotel standbys. With Fxcal closed time feature you can follow along. When it closes out, check the standby, you'll see it won't be there anymore.
