My manager is a great guy, kind, thoughtful, clever, funny and is very supportive! I actually felt that we were becoming close friends - or so I thought.
I went out with work friends last night and I’ve been left wondering if he’s manipulating me and why he’d even bother. I’m in a relationship so there’s no sexual motive either!
These are the ways that colleagues feel he’s not genuine and manipulative.
He compliments my work - he also does this with colleagues.
He compliments my appearance and personality- nothing big, things like you look nice, you’re a great person etc- he also does this with colleagues they’ve shared that they believe that this is a form of manipulation and it makes them feel uncomfortable 
He makes me feel important and special - colleagues state he does the same to them! One told me last night that she’s fallen for him and it’s all in his grand plan for team dominance? 
He texts me out of work hours and talks to me about his personal experiences, he doesn’t do this to colleagues.
I’m a hard worker and good at my job, he doesn’t need to manipulate me to get me to work harder - so why bother. And more to the point, would he be manipulating an entire team?
