I was at work last night. I work night shift. The senior said to me no one better cross me or say anything bad about me that includes you or anyone else. This made me feel really uncomfortable and I didn't say anything in relation to this comment, what should I have said to him. I would only speak to someone about a senior if I felt they weren't doing their job or just delegating an unreasonable amount of work, that was unreasonable to beable to achieve. He then went to sit in the office while I was left to complete all checks on my own. Previous to the remark we were chatting about a course im working on. So the comment was totally out of the blue and not related to anything we were chatting about?
