one of my direct reports is very enthusiastic at her job. She is supposed to be on annual leave just now however, she has agreed to attend a meeting with another organisation during her leave without checking with me first. She has done this a couple of times I think she feels like she has to do these things even though I’ve asked her not to email after hours or on her holiday. I don’t want others to feel they have to stay in touch on their time off. How do I rein her in without dampening her enthusiasm?
