So I'm an employee in a small business. I'm one of the more experienced and therefore senior members of staff. Recently I asked a junior colleague to do something (a fairly simple task which even a new graduate would be expected to do, and which I would happily do myself even though it isn't my area of expertise). I got a lot of grumping about how it wasn't something the staff member was comfortable with doing and they might get it wrong and then get in trouble and lots of sighing and drama. This person probably wanted myself or a colleague to rearrange our own work to do this job instead. To be perfectly frank I'm sick of this individual stropping about being asked to do the work they are employed to do. All of us have to do things we'd rather not, it's the nature of our job, and life is much nicer for everyone if we can work together to get things done with good humour.
Anyway, I stood my ground and the job got done but not without a lot of stomping feet and grumping. I talked the staff member through the task, giving suggestions for action depending on the outcome, so it isn't like no support was offered. And this individual has several years experience so they aren't exactly being thrown in at the deep end.
I'm taking the attitude that childish behaviour will result in being treated like a child so I totally ignored the stroppy crap and stood my ground. But it's terrible for morale and I'm not sure if there's anything else I could be doing. My seniors are aware and supportive but the challenges come with handling the huffing day to day
