No doubt - there are many of these workers in the Office but I'm also seeing many stragglers doing fuck all and also delegating jobs out that they're themselves fully capable of doing but instead of walking 100 yards sending an email + WhatsApp.
While I don't use WhatsApp things get cycled down other channels and it annoys me no end. I'm a busy person 80% of the time but because these leeches can't organise their weekdays they then try their best to offload their, work.
Delegating is fine so long as they're staying busy. I'm fine with my manager being in lots of meetings, because that means that I don't have to attend those meetings and can focus on doing my job.
Definitely a fair point and I imagine it varies highly between industries/companies. I just get to see lots of redundant actions that are simply, redundant, just like the perps in the OP :(
