I am after some advice on a situation at work. I have been in my current role for 10 years and i am confident in my job. I plan my workload and always manage to complete the tasks given to me. But recently my supervisor has been constantly watching me asking me how long it will take to complete tasks when I have just started doing them and then saying once you have finished it can you do XYZ. He doesn't do this with other staff in fact he doesn't monitor them at all. It's starting to knock my confidence and upset me. I like my job but the past few weeks have been tough.
