I think for some jobs it makes sense to have on-call as part of the job description, but it's heavily overused. If there isn't imminent danger I don't think it should be ever required to force someone to compromise rest. If it's just a question of product uptime then you should have enough people and pay people extra to be on-call. And don't deploy things at 5pm on a Friday.
