I am A or B- I don't want to say which do it doesn't skew answers. I've not included salaries as a stealth boast - just for context in terms of level of post.
A - senior manager in a business support function line managed by B. Started £75k role in late January- job is approx 1.5 hour commute each way from A's home. Notice in first year is 1 month, after that it's 3 months. Enjoying the job, excellent feedback and has consistently fed back how committed they are to role/organisation. Resigned on Friday for a new role closer to home - about 25 minutes- on a little bit more money. Has given 1 month notice including a week of which they are in a precooked holiday. A says they didn't aim to mislead - but the job came up and they went for it. Feels that B has taken the resignation personally.
B - A's line manager - senior senior manager. Really pleased with A's work. Received resignation on Friday. Upset, disappointed and a bit pissed off that A has been lying about commitment to role as would have taken another candidate on if it had been known they would leave so soon after joining. Has offered A payrise and flexible working to stay but A still wants to go. Has fed back to A that the move is career limiting due to changing sectors and that they do feel personally let down.
Who is unreasonable here?
