I worked as a technical PM for a medium-sized adtech company in NYC in charge of 2 technical teams, and the business intelligence team.

On Thursday I was informed by the lead PO and HR that leadership had decided that the project management office was no longer necessary for the company and all three of us, the director and the two technical PMs, were being let go. None of us were given any notice.

They offered me 2 weeks of severance pay and I negotiated it to 3.

So I have been seeing a guy for 4 months. We have a pay disparity.. he earns less than I do (by quite a bit). He has mentioned a few times that he’s worried I’ll get bored of him when I know he can’t afford the same things I can. I think we are beginning to move past this, but now he’s starting to mention things like ‘I am really broke this month’, and last weekend he told me his mum has lost her job and he’ll have to probably pay her rent. I have a lot of sympathy for his situation … tbc
