My old boss let me know that once I was done school I can return to my position, as I had an internship. I let him know Friday that I would be interested in being rehired. He said he would be following up on Monday, I assume with his senior manager. How long should I wait to reach out to him to check where he’s at, if he doesn’t reach out? I was thinking this Friday but don’t know if that’s long enough? What would you all do?
