Yeah I wonder this too. It can't be the case that every other worker there is getting a lift!
This would drive me batshit, and I wouldn't do it long term... I wouldn't expect my DH to do it for me either.
One of DH's colleagues worked 7-8 miles from where she lived, and she did shifts (sometimes an early start - and sometimes a late finish ... And she couldn't drive/wouldn't learn,) so her husband had to take her to and fetch her from work. 4 days a week.
She worked 7.30am to 3pm, and 3pm to 10.30pm So he would be at work 9.00am to 5.00pm, and have to take her for 7.30am (so up at 6.30am even though he didn't need to leave for his job til 8.40am!) And when she was on lates, he got home from work at 5.30pm and had to go out to get her at 10pm!
She got to work and from work (when she finished at 3.00pm and started at 3.00pm) on the bus. But the early starts and late finishes, her husband had to take her/get her as there were no buses running at this time.
Why on earth someone would get (and stay in) a shift work job that has no public transport to it - (or none half the time) - when they can't drive just baffles me. No WAY would I do this for anyone. Take them and fetch them from work all the time. I think it's a cheek to expect anyone to do it!
tl;dr, this woman's husband had to give up driving for a year. He was epileptic, but hadn't had a seizure for about 7 years. He had one this one day, and it was reported to the DVLA and his licence was revoked. He got it back after a year, but she had to get a job with bus times hours as she couldn't get there on early shift - or back on lates! I bet her husband was glad!
@stripeyrain If he could walk it in half an hour, he can bloody cycle it quickly! I don't wanna go all Four Yorkshiremen, but I used to walk 30 minutes to work - and back - for some years. (1.6 miles it was, 3.2 mile round trip.) When we moved further away, 3 miles (6 mile round trip) I cycled. (I could drive but didn't have my own car, and didn't need it as I could get to work on foot or by bike!) There was a bus, but it took at LEAST twice as long!) Walking and cycling kept me fit too! 
TELL HIM TO GET A PUSHBIKE!
