I have NC for this for obvious reasons. 3 months ago I started a new job, 6 months probationary period. It's become glaringly obvious that the working environment is not the right cultural fit for me and nor am I the right cultural fit for the working environment. It's a part-time job (I was slightly iffy about taking a salaried role if I'm honest because I'm so used to being my own boss now, having been self employed for years, but the money was good and they promised me a load of flexibility which hasn't materialised) and the rest of the time I am self-employed so my plan is just to continue with being self-employed (I have a waiting list of clients so this shouldn't be an issue). I've given my week's notice per my contract and they asked if I would stay until they recruited a replacement. I declined politely, as I'm in now way legally obligated to stay longer. They've kicked off and threatened to basically sue me for wasting their time?! They don't have a leg to stand on surely? The contract specifically states, 6 month probation period, 1 weeks' notice.
