I was supposed to have my 1:1 meeting with the director a couple of weeks ago but it never happened. He had to cancel and then never rescheduled. I used to meet monthly with my previous manager.
I try to tag up with all my employees at least monthly. I work along side some of them on a daily basis so the formal meetings are shorter. When I meet with the other employees monthly, those meetings tend to be longer to understand how things are going and discuss career development items.
My employer changed from a mid-year/end of year feedback cycle to a quarterly model, which increases my workload and formal documentation.
