I’m currently working from home as a Business Support Assistant within a team of 3. The workload is heavy and has continued to be so during Covid and beyond. I’ve struggled the last 4 weeks with an aching arm and occasionally a few shooting pains through my fingers every now and again. I spend 6 hours each day on the PC. I’m hesitant to speak to my Manager as in the past she’s been unsupportive. What should I do?
