I work for a big company on a temporary assignment basis, so am on their pay role permanently and work wherever they need me, transferring between different departments. Last week I left a new assignment after a few days as it wasn't a good fit for me. I have never done this before and was worried about leaving. They were disappointed but wished me well. I now have a new assignment starting next week, still as same big company. Ex supervisor emailed me today and asked me to change my Linkedin profile which states I still work at company. She does not know I have new role starting next week (within same company) however I think this is bloody cheeky and rude since what business is it of hers? Is she stalking my Linkedin profile? Plus we left on good terms so I'm a bit surprised by this random email. Do I reply and say get lost I actually have another placement starting next week or just ignore because I don't think I need to justify myself?
