What does revisiting an old job mean?

I was in Haslemere Post Office, re-employed as a postman delivering mail at the same office I did 30 years ago. I was not sure I would going to get paid. These days, I had no contract of employment and the boss was nowhere to be seen. Always "at a meeting". So I was eager to get going.

Except nobody would tell me what round I was doing. I couldn't find the notice board that normally carried our rotas, nor was there a sign-on sheet any more. People were supposed to remember their times. I remembered from before I had Lion Lane, and Round 9, which was Shottermill, and Round 2, which was the hilly one down the Petworth Road. Nobody around would tell me. The best I got out of them was "the trouble with you before was that you stirred things up too much".

I hung around for a bit, and then reasoned that whatever frame still had a pile of letters on it would be the one I was supposed to be doing. Except there were no letters and no frames. Someone told me they re-organised the office, so there weren't any prep frames any longer. The old sorting office was not used, and was sold off for redevelopment. Our office now was where the bikes used to be stored, a warren of cubbyholes and corridors. Nor, it seems were there any letters.

I hunted around a bit longer and found a pouch with a few dozen letters inside them, which I presumed was my delivery. Except all the letters were addressed to other offices, especially Hazelmere in Bucks. So I got out a red Tempo pen I'd had for years and started writing on them all "Not Haslemere, Surrey" hoping that it would get back to someone important, who might do something to run the office a bit better.

Then I woke up, and of course in real life I have no job. They don't exist for my sort.

Is my dream telling me something about the state of British industry?
