It's two colleagues in particular. To say at the start I get on with both these individuals very well at a professional and social level. There are certainly no personal issues between us at all. We all work in the same relentlessly busy organisation where there is a good deal of electronic communication needed.
And yet, from these two people in particular whenever I text or email them in context of work I have no response or acknowledgement. Which leaves me irritated. A brief one word answer would usually suffice - eg Thanks - depending on the context of course.
But there's usually......nothing. Which sometimes leaves me wondering - esp with emails - have they actually seen the message? (I can tell with text but not email) Do I need to send another one just in case? Also, to know what they are doing with the message is usually helpful to me in moving forward with stuff - I'll know so and so is aware of such and such etc.
I can only think that they imagine such messages just don't NEED a reply. By contrast other colleagues do reply. This includes the boss - a very hard worker who probably has less time to spare than any of us - who always acknowledges, usually within an hour, any message I occasionally need to send to him.
But apart from anything else is it not simply good manners to reply to a message?
So..
YABU - chill out, this is a busy work situation, they've got the message, you've done your bit, just get on with your day.
YANBU - it is quite reasonable to be irritated not to receive an acknowledgement of a message.
