There is a very clear line in that you chose that commute. You can find housing near your employer. You have a laundry list of personal reasons why that housing is not right for you but the fact remains you chose to have those things and commute instead of living nearby and sacrificing those things.

The employer requiring you to do something as a condition of continued employment is clearly, well obviously not, an act that should be compensated for. They could let you leave 15 minutes early to go through security check, they just don’t want to because, apparently, they don’t have to.

I have no doubt that you will find a group of people on the other side of the line there who think employers should have to pay for commuting time and obviously this case proves there are people on the other side of this line who think they shouldn’t have to compensate you for going through security time. However I would guess that the majority of people will agree that hardships you impose on yourself are your responsibility while hardships the employer imposes on you should be their responsibility.
