- Can one desecrate/be michalel Shabbat for the sake of his livelihood/parnassah at risk? For instance, if one has a flock of sheep (his entire livelihood) and lives in an area highly prone to thievery, can he make rounds on Shabbat with a flashlight, assuming that is the only option to protect his livestock?
- Can he turn the flashlight on before Shabbat & keep it on for the whole Shabbat?
If he must turn the flashlight on and off to conserve energy is that allowed (in a scenario where he is stuck with no other option)?
Can someone besides the owner turn on the flashlight to help out?
