I am lucky right now, because I can park my bike inside the office, near my cube. I would really like a bike locker. I think it is great if a company provides one. I would be happy to pay for the full year, whether I used it at that time or not. I just know that I would use it the majority of the year.
Offthegrid, I take all my work clothes to the office over the weekend. Again, lucky to have a fairly secure place to hang them. I make sure I have extra underclothes hidden in my desk if, heaven forbid, I don't have what I need. It took awhile to get all the stuff I need put together into a bag I have under my desk. We don't have a shower at work, so I do a sponge bath when I get to work. Luckily, I ride so early in the morning, I don't have any problem monopolizing the one "private" bathroom. It does mean that I have to make a trip up to work over the weekend. But, I have a birdfeeder at work and I go up there anyway to fill the feeder at least one day over the weekend.
