As a fellow believer, I agree with your sentiment, but add the following-
1 Timothy 5:8 "But if anyone doesn't provide for his own, and especially his own household, he has denied the faith, and is worse than an unbeliever."
In Matthew 20, Jesus tells the parable of paying the 3 sets of workers hired at different times of day the same wage. His answer to the man who protests is this, "Friend, I am not being unfair to you. Didn't you agree to work for a denarius? Take your pay and go. I want to give the man who was hired last the same as I gave you. Don't I have the right to do what I want with my own money? Or are you envious because I am generous.
The burden of provision, from a Christian perspective, is on the worker not the employer. No one owes any of us a job that will sustain us. We have to work for it.
The parable you site is a teaching concerning God's unearnable grace and seems unrelatable to an employer's responsibilities to my thinking.
Of course employees do have responsibilities as do parents to take care of the family... but none of this lets the boss of the hook. He has a mandate - a command about his actions.
