Interesting article
I would argue you do have a very successful career, both in term's of £ value -contributing to running a family and home and 'job satisfaction' (raising happy healthy kids/everyone's nice home life).
If his job involves sales, finance, accountancy etc... (I'm assuming an understanding of what it costs to bring in outside labour) tell him to tot up your £ value to the Family Firm.
And as he probably considers himself your line manager (in his head) ask for a review of your working conditions, access to holidays/sick and lunch breaks. If you don't get a good enough answer, tell him you're off to see HR (your solicitor).
How's them apples...
By the way - if he didn't have such a settled home life, whose to say he would have been able to devote time to the job to get this promotion. An Opportunity Cost Analysis.
Lastly, if he can't get everything done during the working week (flat out mon-fri) Without it over spilling into the weekend. Or being so knackered he can't spend anytime with the family, then I would suggest the job is too much for him.
When the kids are older, perhaps they would like to do a performance review of their dad. Wonder how he would score on that?
Ggrrrrrr - this topic makes my teeth itch.
