Promotion?
Haahaahaa.
When was the last time you worked a low-paid, dead-end job? Most low-paid jobs are by their nature dead-end.
As for moving, well, let's see.
The big problem I foresee with, 'Hmm, there aren't a lot of jobs here, I think I'll move to [insert larger town/city] so I can make £5.50 at Tesco,' is that housing generally costs A LOT more in areas with lots of job opportunities.
So then you have a low-paid worker in a high-cost areas.
And these high-cost areas, let's just use the city where I live, Edinburgh, have a HUGE problem with homelessness as a result.
Council housing? There's a laugh. Association housing is amalgamated with council so it's all part of the same parcel.
Good luck! Even if you're homeless, the best they'll offer you is temp accommodation.
Moving also costs.
A lot. There are deposits and moving costs and first months' rent.
So we're talking at least a £1000 outlay.
That's a lot of dosh.
Oh, and ever tried to get a job when you're living in another area? I mean, the low paid type?
Good luck!
