to cage or not to cage, this is the question

In the corner of the office we have an area that is referred to as 'The Cage', it is locked and has partly wire mesh walls, where the Special Delivery items are sorted and other important stuff stored. Today the manager asked me if I was interested in taking on an indoor job, working in the cage. As part of the revision there is a reallocation of all jobs within the office, based on seniority (how long each person has worked for Royal Mail, I have eight years eight months), and whether you are full time or part time. He knows how to get to me because he says the job needs someone well organised and professional, and I am a sucker for a bit of flattery. I would still be doing the same hours and days, though sometimes coming in earlier to open the office! So I am weighing up the pros and cons of a distinct change of role.

pros:

being inside in the warm

not so physically tiring

interesting variety

getting to know how the office runs

more responsibility

having to learn new stuff

can always do some delivery on overtime if I miss it

cons:

being inside

missing the physical activity

not really being a 'postie' any more

feeling a bit like it is a softie job

having to do packet delivery one day a week

I am trying not to make a gut decision based on the fact that I have had a crappy hard work week and cursed the whole process of going out and putting letters through people's doors. I had not really considered the job that seriously before because I did not know what it involved, but now I am in a quandary.
