A Phased Return to Work - Pros and Cons

I have been at work for what must be three and a bit weeks, now. Work have been very supportive in allowing me a phased return, which means that I have only just worked myself up to my full hours. I am a teacher who works four days a week, Monday to Thursday. There is absolutely no doubt that I have found going back to work particularly difficult. I had been out of work since March, and what with the summer holidays, this meant going back to work at the beginning of September, some almost 6 months later. This was certainly a shock to the system.
