Sarah is full of tit and prone to exaggeration. He might work long hours occasionally, but mostly that’s a convenient excuse to get out of doing anything kid or house related. I bet Brad wastes a tit tonne of time and when Sez leaves the house, he’s upstairs having the time of his life. She’d also be down in the toilet whining at him all day or telling him one of her inane stories.
I don’t know why Sez thinks it’s a flex. If he worked for me, I’d be putting an end to his work from home because he clearly can’t get his duties done in a reasonable amount of hours. Needs to be more closely supervised. If he was still struggling to get his work done or delegate his tasks, there’d be a conversation about performance management.
