Should slaves push

A silly question you might think but one that i often ask myself in the light of how MG and i live our lives.

i have again this evening, watched my Master push himself to get up and out for work when he is obviously totally shattered, yet he does it, again and again, day after day during his shift and each day i say to him that he cannot go on like this... there are just not enough hours in the day for him to work the hours he works, added to that the traveling time...and in there somewhere, find enough time to sleep as well. He starts a new shift still tired from the last, whilst he also tries to find time for me and the kids as well.
It breaks my heart to see him like this and yet, what can i do... i try to make life easier for him but it is not enough and i have to stand back and watch him work himself into the ground.
We both know what needs to be done, in the immediate and foreseeable future, he needs to talk to his boss, reduce his work load, even go back to a 4 on 4 off shift ( he currently does 5 on, 3 off) and see how that works, long term , he needs something with less hours, and more local to home, but those kinds of jobs are few and far between and some would say we should be happy that he is in work at all, many are not.

We should also be glad that at least we have a little time to spend together during the 8 day cycle and of course we are, some ( particularly long distance relationships) don't see their other halves from one month to the next or even longer sometimes. But this isn't about what time we have together, this is about my Master and his needs, not mine... and right now..his need is for sleep.

The title asks, when or if a slave should push her Master and my thinking is, that without nagging i feel i must try and keep trying to get MG to pin his boss down and get this problem sorted before he makes himself ill. In the best interest of...and believe me, it is in his best interest because he cannot go on like this.

The difficulty arises in that things are not all they seem to be right now, with his work, we are sure there is some kind of "Take Over" afoot, but trying to pin someone down to find out who is actually running the company he works for is like trying to get a blood out of a stone. If he could find out who he should be talking to, well, at least that would be a first step, following that, he has to do something about these hours because this really is becoming a major problem.
MG cares for all my needs in one way or another, its time i started to care for his and as i cannot do what needs to be done, only he can, all i can do is to encourage him to seek out whoever it is that can have some effect on his current work situation.

i do hope that happens soon as i am become more and more worried about his health and well being. i dont want to become a nagging other half, its not for me to tell MG to do anything, but its so hard to see him like this and the only way for that to change is for him to find out what he needs to and take it from there but, catch 22 again, he has no time to even talk to whoever it is in charge of this place where he works, he walks in to do a night shift, they walk out.... how is he ever meant to talk to anyone and yet... he has too... and i am at a loss as to how, but if i just stay quiet and let another day/week pass, am i being a good slave to him and allowing (if thats the right word) this situation to continue without at least trying to push him a little to get something sorted at whatever cost.
