I have expectations as a leader in my organizations for other employees who are in a leadership position in my company. One of those expectations is, if I call or text you on off hours, weekends, vacations, etc., for something that is urgent to the business, I expect a reply in a rather short time frame.
Some people would not like that. I don’t care. You’re a leader, the business needs you, there’s no time clock for that.
That expectation is set for someone at a leadership level in my organization. They know this expectation before taking the job.
