You actually sound a bit my husband and I. We both have our limitations, and have "enabled" each other in those ways. But we keep reminding ourselves, that there are more degrees of freedom to do things that are out of our routine. If you wanted to get a better paying job, but then giving up the car duties, maybe there is a way to make that happen. Don't rule something out just because the transition might be hard.
I am not against going out of my comfort zone and trying for a new & better job. However, unless she gets her driver's license and can share driving duties, it just isn't realistic.
My wife and I are in a similar situation. We do love doing everything together. We have been married a few years now and just had our first child. Since we only have one vehicle and she currently doesn’t work (in the past she did do some babysitting and had a nice paying online job; now she’s working on her undergrad) her not being able to drive wasn’t as big of a deal.
Currently, right before our child was born she got her permit. She passed the written test easily with a course online. (see [url=idrivesafely.com]idrivesafely.com[/url]) She already attempted the driving test on the practical side of things before the baby came and didn’t pass. But we need to keep on trying. Our goal is for her to get her license this year. There is a lot of fear associated with this but I always try to encourage her and help her see the light at the end of the tunnel.
We’ve talked things over and even though having a second vehicle would result in added costs it would be a great benefit especially with the doctor’s appointments, errands, grocery runs, etc. Plus it would give her a little more independence and take some of the pressure off of me.
Also keep in mind that part of being in management is learning to deal with stressful situations and helping others move forward. Conflict resolution is part of this as someone already mentioned. I think the best thing you could do would be to encourage her to take small steps towards resolving the situation with her subordinate.
Of course for anything to change people have to want to change. I’d say check the website out and talk it over with your wife. Hope this helps.
