Don’t forget everyone - that the real hourly rate you work for is the actual hours you spend away from your home divided into the NET takehome pay.
Eg. Leave home @ 6.15am, clock on @ 07:00, take an hour off 13:00-14:00 for lunch, book off @ 17:00 home in the evening traffic @ 18:15.
SO monday-friday you’re really putting in 60 hours per week - 60 hours where you are not at home with your wife, kids, private life etc. available to do stuff you want.
Now if your job gives you a takehome pay of £600pw - then that job I’ve just described effectively pays £10ph - got it?
If you can’t push up the headline hourly rate in your workplace - then concentrate on doing the job more efficiently instead, and “Make time” to effectively increase it. 
The same job I described above, but this time with the figures massaged as follows - looks like this:-
Leave home for work @ 06:45 Clock on 07:00, Take same breaks as before, but this time you’ve got away 45 minutes earlier, and not only missed evening traffic - but you are setting off home @ 16:15, and are home by 16:30.
That’s a total of 10 hours round turn per day instead of 12.
You’ve just reduced your Door-to-Door working week from 60 to 50 hours, and pushed your effective hourly rate up 20% to £12.00ph - without even getting a pay rise!
All you’ve done is make 45 minutes on your duty. I do NOT recommend doing this by “taking your break on the derv pumps” btw. Just become efficient at doing your regular job, so you can do it standing on your head so to speak.

Anything that cuts down your commute time - helps a LOT as well of course!
